Two AMBER (African Meridian B-field Education and Research)  magnetometers were installed in the Philippines. The first was installed at Manila Observatory’s Davao station in Matina Hills in 12 February 2016 and the other at the Magnetic Observatory of the Philippine National Mapping and Resource Information Agency (NAMRIA), Muntinlupa in 13 June 2016. The principal investigator of the AMBER project is Dr. Mark Moldwin from the University of Michigan, while the principal investigator of the AMBER expansion project is Dr. Endawoke Yizengaw from the Institute of Scientific Research of Boston College. The installations in the Philippines were led by Dr. James Simpas and Clint Bennett. Dr. James Simpas is an Assistant Professor of the Department of Physics of Ateneo de Manila University and head of Urban Air Quality / Instrumentation Technology Development and   programs (UAQ/ITD) at Manila Observatory. Clint Bennett is an Instructor at the Department of Physics of Ateneo de Manila University, Coordinator of the Philippine MAGDAS (Magnetic Data Acquisition System) Network, and research staff of the Upper Dynamics Program of Manila Observatory.

The AMBER magnetometer network was built by Boston College to gain a more complete global understanding of equatorial ionospheric motions. AMBER magnetometer stations are used to connect the European IMAGE-SAMNET-SEGMA magnetometer arrays to low and dip-equator latitudes, and link up with South African Intermagnet and Antarctic magnetometers in the southern hemisphere. Amber aims to provide complete meridian observation in the region and filling the largest land-based gap in global magnetometer coverage.  The two AMBER installations in the Philippines at Davao and Muntinlupa were funded by the Air Force Office of Scientific Research (AFOSR).

A. Installation in MO-Davao Station

Last 12 February 2016, Dr. Endawoke Yizengaw of Boston College was accompanied by Dr. James B. Simpas, the head of the Instrumentation Technology Division of Manila Observatory, in the installation of an AMBER magnetometer in MO-Davao station at Matina Hills, with the help of MO-Davao staff Efren Morales and Ruel Narisma.

Davao is an important location since through it passes the magnetic dip equator where the geomagnetic field is nearly horizontal and not tilted from the vertical unlike at the poles. Along the magnetic dip equator flows the Equatorial Electrojet (EEJ), which is a narrow ribbon of eastward current that peaks around 1:00 pm local time. During geomagnetic storms, ring currents are also formed in the equatorial region at 3 to 5 times the radius of the earth (about 6,378 km). The EEJ and ring currents generate magnetic fields around them which can be measured by the magnetometers near the equator.

B. Failed Installation at Manila Observatory

Last 9 February 2016, a few days before the AMBER magnetometer was installed at MO-Davao station, Dr. Endawoke Yizengaw met with Clint Bennett, Dr. Quirino Sugon Jr, and Dr. James Simpas at Manila Observatory. Dr. Yizengaw brought with him the box containing the AMBER magnetometer sensor, cable, and logger. But after some tests, the magnetometer data received was too noisy.

Clint Bennett and Dr. James Simpas also tested the magnetometer readings at the Jesuit Residence near the High School area of the Ateneo de Manila University Campus last 24 February 2016. The data was still noisy. They tried to test again 4 days later for about 30 min. The same noise problem. A new location is needed.

C. Installation at Magnetic Observatory of NAMRIA in Muntinlupa

Top right: Clint Bennett and Ezequiel Manalac of MO unloads the AMBER cables. Bottom right: Henry Nayve and Clint Bennett of MO sets up the internet connection of the AMBER sensor in NAMRIA office.

Last 5 March 2016, Clint Bennett contacted CPO Alex Algaba of the Magnetic Observatory of NAMRIA (National Mapping and Resource Information Authority), and asked permission to install the magnetometer at the observatory in Muntinlupa. A month later, CPO Algaba informed Mr. Bennett that Commodore Jacinto M. Cablayan, Director of the Hydrography Branch of NAMRIA, had obtained the permission from NAMRIA for the installation of the AMBER magnetometer.

NAMRIA was created in 1988 by DENR (Department of Environment and Natural Resources) to “provide the public with mapmaking services and to act as the central mapping agency, depository, and distribution facility for natural resources data in the form of maps, charts, texts, and statistics.” NAMRIA’s Director is Dr. Peter Tiangco who manages four technical branches: (1) Mapping and Geodesy, (2) Hydrography, (3) Resource Data Analysis, and (4) Geospatial Systems Management.

The Hydrography Branch acquires and analyzes hydrographic and oceanographic data for promoting navigational safety and oceanographic research. The outputs are nautical charts, navigational warnings, and tide and current predictions. The hydrography branch also collects 12-month geomagnetic data from magnetometers hosted by NAMRIA, which are part of OHP (Ocean Hemisphere network Project) of the University of Tokyo and the MAGDAS/CPMN (Magnetic Data Acquisition System / Circum-pan Pacific Magnetometer Network) Project of Kyushu University. Now, the hydrography branch also collects 12-month geomagnetic data from the AMBER Netowrk. These data are used together with those from 18 repeat stations all over the country to construct data products such as geomagnetic maps.

Last 14 April 2016, Clint Bennett together with Exequiel Manalac and Dr. Quirino Sugon Jr. visited the NAMRIA Magnetic Observatory in Muntinlupa, bringing with them the AMBER magnetometer set. They were welcomed by CPO Alex Algaba. Because of the length of the magnetometer cable is not long enough, the magnetometer was buried only a few meters from the iron gate, such that whenever the gate is opened or closed, the magnetometer readings jump.

On 13 May 2016, Clint Bennett returned to NAMRIA together with and Henry Nayve and Dr. Quirino Sugon Jr to adjust internet settings of AMBER’s BeagleBone, so that the data would show up in the AMBER website. The set-up was finished about noon.  Then the MO team, together with CPO Alex Algaba, traveled to NAMRIA headquarters in Manila. There they were received by Commodore Jacinto M. Cablayan, Director of the Hydrology Branch of NAMRIA. Clint Bennett and Dr. Quirino Sugon Jr discussed with Commodore Cablayan and his staff the AMBER network, the Manila Observatory, and NAMRIA’s interest in geomagnetic field data. The action step agreed in the meeting was the creation of an MOU between MO and NAMRIA regarding the AMBER installation.

On 13 June 2016, the magnetometer was transferred to its final location, more than 200 m from the iron gate. It’s now in the woods behind magnetometer house, far from vehicular or human traffic.

Ateneo Physics faculty Dr. Quirino Sugon Jr receives faculty fellowship at ICSWSE, Kyushu University


Dr. Akimasa Yoshikawa, Ms. Kayo Goto, Dr. Quirino Sugon Jr, and Prof. Kiyohumi Yumoto at the International Center for Space Weather Science and Education, Kyushu University, Ito Campus

Upon the invitation of Dr. Tohru Hada, Director of the International Center for Space Weather Science and Education (ICSWSE) at Kyushu University, Dr. Quirino Sugon  Jr. took a leave of absence from Upper Atmosphere Dynamics program of Manila Observatory and the Department of Physics of Ateneo de Manila University from 1 August 2016 to 30 April 2017 to work as Associate Professor at ICSWSE. Dr. Sugon’s stay at ICSWSE was made possible through the efforts of Dr. Akimasa Yoshikawa, the Principal Investigator of the MAGDAS (Magnetic Data Acquisition System) project, who serve as Dr. Sugon’s research supervisor.

Dr. Sugon’s research topic at Kyushu University is seismo-electromagnetics, the study of electromagnetic phenomena associated with earthquakes. This is essentially the same topic which Dr. Sugon, Dr. Felix Muga II, Fr. Daniel J. McNamara, SJ, and Fr. Sergio Su, SJ were awarded the  Loyola Schools Scholarly Research Grant this year: “Seismoelectromagnetics: Finding magnetic precursors of the 2010 Moro Gulf Quake using MAGDAS data.” The grant’s duration is from January 1 to December 2016. The grant funding of Php 300,000 was used for the 6-unit research deloading of Dr. Felix Muga II and the hiring of Christine Chan as Research Assistant.

Below is an interview with Dr. Quirino Sugon Jr. by Ateneo Physics News:

1. Did you have problems with getting out of the country?

Yes. I should have left last 1 July 2016 instead of 1 August 2016, but I got stopped at the Immigration Office at the Airport: I ticked off that I am an Overseas Filipino Worker (OFW), but I could not show an Overseas Employment Certificate (OEC) from the Philippine Overseas Employment Agency (POEA). What I only have is the Certificate of Eligibility (COE) from the Japanese Embassy. OEC and COE sounds the same, so I thought they’re the same. So the Immigration officer sent me to POEA to get my OEC.

After informing the Secretary of ICSWSE, Ms. Goto Kayo, that I can’t leave because of Immigration problems, I went to POEA on the same day and asked for the requirements. There’s a list of about 10 documents to obtain. Essentially, all these requirements are meant to assure POEA the following: (1) I was really invited to work and not a TNT (Tago-ng-Tago), (2) the place where I plan to go is a legitimate business, (3) I am qualified for the position, (4) I am medically fit to work, and (5) I am documented as an OFW. The tough one to get was the labor contract certified by the Philippine Overseas Labor Office (POLO) at Tokyo. Our secretary Goto-san took care of it. So I got all my documents and attended the Pre-Departure Orientation Seminar (PDOS) at POEA. I am now a certified OFW. According to Evaluation Office at POEA, Postdoctorates are not classified as students but as workers, so those who plan to take postdoctorates abroad should really go through the same pre-departure process at POEA.

When I went back to the Immigration office at the end of July 2016, my name was removed from the blacklist and I finally boarded the plane.

2. Did you travel around Japan?

Not much. I once went to the Amazon Exhibit in the Fukuoka Museum with the family of my friend. The Museum is only a walking distance from my apartment in Fujisaki. During Sundays, I go to Daimyomachi Church at Tenjin station for the English mass at 4:00 p.m. or to the Japanese mass at 9:30 a.m. On weekdays, I go to Kyudai Gakkentoshi Station and ride a bus to the Kyushu University, Ito Campus. During weekends, I stay at home to write some research reports. If I’m free, I write in one of my personal blogs: Quirino Sugon Jr and Monk’s Hobbit. The former is a blog on the art of blogging and its related crafts–content marketing, social media, graphic design, creative writing, etc, while the latter is more on politics, religion, and literature. Blogging is my favorite past-time. I can spend hours tinkering with my blog fonts and colors. I also like to read and write long-form content not only for the sake of search engine optimization (SEO), but also to hone my writing craft. Writing is an art, but is also also a science that can be studied with a box of writing tools from Poynter Institute.

I go around Fukuoka City via subway trains. Japanese trains are amazing: they really come on the scheduled time, so you can plan your travel really well, especially if you are transferring from one train to another. To travel outside of Fukuoka, you can take the fast Shinkansen trains.

I first took the Shinkansen when I joined my colleagues at ICSWSE in going to the Ninja Village in Ureshino, Saga Prefecture. I got to wear a Ninja black costume with red sash. One of the Ninja masters lent me his sword and asked me to act as if I am chopping off his head. I was Naruto for a day: walking along a dusty street, throwing shurikens at walls, and visiting old Japanese houses. There is also a flat portrait of Our Lady carved in stone. Our secretary told me that it’s Maria. Perhaps it was carved centuries ago when Christianity was still persecuted in Japan. I have seen a similar portrait before in the Shimabara arc of Rurouni Kenshin (Samurai X).

The second time I took the Shinkansen was last week. I took a 5-hour trip to Tokyo, starting at 9:00 a.m. I arrived in Tokyo about 2 pm and I got lost in the train station. I went to the information booth and asked for the Nijubashimae station. The lady there gave me a map and marked the directions. I thought the blocks in the map are the stalls inside the station. it turns out that I have to go out of the station, walk 3 blocks, and take a subway via Chiyoda line. I was scheduled to give a research at at 3:30 pm at the Asian Office of Aerospace Research and Development (AOARD) , a US funding agency that supports basic research.  I arrived there at 3:45 pm and gave my presentation at 4:00-5:00 pm. It was the same presentation I made in Kyushu University in 1 Nov 2016 on the measurement of the height of Equatorial Electrojet using MAGDAS magnetometers. After my presentation, I took the same subway line as before and rode the Shinkansen at 6:00 pm. I checked the train schedules in the Shinkansen website and realized that I took the wrong train! it was bound for Okayama and not Hakata in Fukuoka. So I went off the train at the first station and changed train for Hakata. I arrived about 11:20 pm in Hakata and took another subway back to Fujisaki. I arrived before 12 midnight, just like Cinderella.

The Tokyo trip was life-changing for me. Terrifying would be a better word. After my Tokyo trip, I felt that I can already travel around Japan, even as far as Sapporo and Hokkaido in the North. Maybe someday, but not yet.

3. What’s your favorite dish?

I don’t know most of the names of what I am eating. I usually eat in the cafeteria and I survive by just pointing my fingers on pictures. I like boiled pork strips, fried flat fish, and miso soup. At home, I cook my own food. I have a rice cooker. One of my favorite recipes are chicken liver, heart, and gizzard boiled with onions in sushi vinegar and toyo–something like Filipino adobo, but I add mushrooms. Other recipes are essentially based on boiling fish, pork, or beef with onions, then add leafy vegetables. I finish cooking in 10 to 15 minutes. I avoid preserved foods because I’m already an old man.

4. How’s your Japanese?

Sumimasen, my Japanese is terrible. I can’t even talk with a 6 year-old who already knows how to ask me “How are you?” in English. During our lunch at the office, I only try to guess what my colleagues are talking about based on a few familiar words accompanied by their hand gestures. Sometimes our secretary would explain to me what they are talking about. I really need to learn Japanese, because my boss, Prof. Yoshikawa challenged me by saying, “Sugon san, I will only speak to you in Japanese.” Also, the doctor of Kyushu University who interviewed me during my medical tests told me, “Next time, when you come back, you should speak Nihonggo.” Hopefully, I can focus learning Japanese this Christmas break. If Nodame can learn French by watching anime with Japanese translations, maybe I can learn Japanese, too.

Recently, I bought a Japanese Hymnal for the mass so that I can learn to read Hiragana and Katakana while plucking the notes in my guitar.I also bought an Order of the Mass in 6 languages: Japanese, Romaji, English, Portuguese, Spanish, and Filipino. I attended the Japanese mass last Sunday and noted the Hymn numbers they use. Next Sunday, hopefully I can already join the singing and participate more in the Japanese mass.

5. Have you published your research?

Not yet. I spent the whole of August doing a literature survey, reading on magnetic measurements of space weather activity, and building my library of pdfs that I store in my Google Drive. I may not be able to access these pdfs in the Philippines, so it is best to store them now. I’m using a name_year_title filing convention. The Google Scholar Chrome extension has been a great tool for me for building up my bibliography.

In September and October, I did my computations while writing my manuscript in LATEX, a programming language for typesetting mathematical paper which is based on the principle, “What you see is what you want.” LATEX does the hard work for you in creating the bibliography, numbering the equations, positioning the figures, and formatting the document, so you concentrate on writing the content. For my computations, I’m still a paper and pen guy, though recently I discovered that I can perform complicated triple integrals using MATHEMATICA, a computer algebra system from Wolfram Research that my research supervisor, Yoshikawa sensei, gave me a license to use. Most of theoretical physics research is essentially accounting for the variables and signs as you go from one computational step to another. If a software like Mathematica can do this faster, then so much the better. I can then focus on checking out whether the equations make sense, by checking the assumptions used in the computation or finding the limits as one variable goes to zero or infinity.

In November, I wrote some reports for the ISWI Newsletter. ISWI is the International Space Weather Initiative, “a program of international cooperation to advance the space weather science by a combination of instrument deployment, analysis and interpretation of space weather data from the deployed instruments in conjunction with space data, and communicate the results to the public and students.” The Manila Observatory manages several ISWI stations: 6 MAGDAS magnetometers, 3 SCINDA receivers, and 2 AMBER magnetometers.

This December, I made a research presentation at the AOARD office in Tokyo. The LS Scholarly Grant report on our Seismo-electromagnetics work on the Moro Gulf Quake will be submitted this week. It has some promising results, but we still need a few more months to finish the article, which is the primary reason why I came here in Kyushu University. Making a claim that we can predict earthquakes from magnetic field measurements is audacious, so we need to be very prudent and exhaust all sources of errors using all statistical techniques that we can think of. We are now extending the scope of the project from 23 July 2010 to the whole of 23-30 July 2010 when 31 earthquakes occurred in Moro Gulf. After this, we’ll extend further to the remaining 10 earthquakes in 2010 in the same area. Hopefully, this would give us more sample events to test our theories.

6. How big is the data that you are working on?

Big data is now the buzzword in business and technology:

Big data is a term for data sets that are so large or complex that traditional data processing applications are inadequate to deal with them. Challenges include analysis, capture, data curation, search, sharing, storage, transfer, visualization, querying, updating and information privacy. The term “big data” often refers simply to the use of predictive analytics, user behavior analytics, or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set.[2] “There is little doubt that the quantities of data now available are indeed large, but that’s not the most relevant characteristic of this new data ecosystem.” (Wikipedia: Big Data)


Dr. Quirino Sugon Jr before an Maple tree in Autumn at Kyushu University

In seismo-electromagnetics research, we are also processing big data: we have a database of 1-second resolution 3-dimensional magnetic data from 5-6 stations for 5 years, which can run to a total of about 3 GB. Well, the size may be small compared to terabytes (1,024 GB) of business data for consumer analytics, but 3 GB cannot anymore be handled by MS Excel or Google Spreadsheets. We also have no clear cut idea on what type of magnetic anomalies we are looking for, so we try out different anomaly detection techniques for different variables and see if the anomalies can be explained by the physics that we know.

We store our data in terabyte data storage discs. Then we use PANDAS (Python Data Analysis Library)PANDAS (Python Data Analysis Library) to extract the information that we need. I don’t know much about Python programming, except the basics of what it can do, so that I can talk with Dr. Muga and Christine Chan on how the algorithm may be implemented in PANDAS. We usually meet every Wednesday for one hour of audio call in Skype starting at 12:00 noon, Philippine time. Sometimes I got confused since Japan is one hour ahead. But I am glad that modern technology has made research collaboration easier for scientists working at different countries, so that it does not really matter much whether I am at Manila Observatory or in Kyushu University.

There’s a Python meeting in Ateneo de Manila University this January 2017. Christine and Dr. Muga are helping out in the logistics for this event. The Upper Atmosphere Dynamics Program of Manila Observatory, for its part, made a commitment to use Python. Python has clean syntax, powerful string operators, and extensive libraries. It’s open-source. We don’t pay anything for using it. Hopefully, next year, we can begin using the Python module pyglow for space weather research:

pyglow is a Python module that wraps several upper atmosphere climatoglogical models written in FORTRAN, such as the Horizontal Wind Model (HWM), the International Geomagnetic Reference Field (IGRF), the International Reference Ionosphere (IRI), and the Mass Spectrometer and Incoherent Scatter Radar (MSIS).

7. Any parting words?

Seismo-electromagnetics is an emerging field and scientists are looking for anomalies not only beneath the earth, but high above in the ionosphere, so that tools for studying the ionosphere–magnetometers, ionosondes, GPS receivers, and satellites–are also used for finding electromagnetic precursors of earthquakes hours or days before the quake. Next year, China National Space Administration and the Italian Space Agency shall launch the China Seismo-electromagnetic Satellite:

CSES (China Seismo-Electromagnetic Satellite) is a scientific mission dedicated: to monitoring electromagnetic field and waves, plasma and particles perturbations of the atmosphere, ionosphere and magnetosphere induced by natural sources and anthropocentric emitters; and to study their correlations with the occurrence of seismic events. More in general, CSES mission will investigate the structure and the dynamic of the topside ionosphere, the coupling mechanisms with the lower and higher plasma layers and the temporal variations of the geomagnetic field, in quiet and disturbed conditions. Data collected by the mission will also allow studying solar-terrestrial interactions and phenomena of solar physics, namely Coronal Mass Ejections (CMEs), solar flares and cosmic ray solar modulation.

So what we are doing is not a far-fetched idea. Others have invested more time and resources on seismo-electromagnetics research. The race is on.

Dr. Gemma Teresa T. Narisma, MO’s Associate Director for Research and Program Manager of Regional Climate Systems, gave a 20-minute talk on MO’s Science Agenda and Director Antonia Yulo Loyzaga gave the Closing Remarks. After the program, the speakers and guests were given a tour of Manila Observatory’s Exhibition at the Solar Research Building which showcased the instruments, photos, and other memorabilia in MO’s 150-year history.



Manila Observatory’s 150th Anniversary Exhibitions: Discoveries, Transitions, and Frontiers


Stamp issued by the Philippine Postal Corporation in celebration of Manila Observatory’s 150th Anniversary. The stamp was designed by Randell G. Teodoro, research staff of the Solid Earth Dynamics program of Manila Observatory.

In celebration of its 150th anniversary, the Manila Observatory presented three exhibitions: Discoveries (1865–1940), Transitions (1940–1990), and Frontiers (1990- Present). The Exhibition is housed at the Solar Research Building. This building was designed to house the spectroheliograph which was operated by Fr. Richard A. Miller, SJ, Fr. James J. Hennessey, SJ and Fr. Francis J. Heyden, SJ from 1965 up to the late 1990s:

“A combination solar spectroheliograph and spectrograph, newly installed in the Philippines at 8-h East longitude is described. The rotatable vacuum spectrograph follows an Ebert design, consisting of a plane grating and two mirrors. These off-axis mirrors are figured sections of one single mirror form and function as collimating and camera mir- rors. The spectrograph system matches the f/24 Gregorian-type telescopic quartz mirror system of 30.5-cm clear aperture, fed by 41-cm coelostat mirrors. The grating drive is wholly within the tank. Spectroheliograph scans are with fixed slits but with a moving image and moving plate or filmholder. Slit jaws are of stainless steel and form slits 76 mm long. Dispersion is 2.75 A/mm in the first order. An 8.3-cm x10.8-cm plateholder receives the spectrogram or spectroheliogram image. Visual monitoring and 35-mm photographs of the solar image at the entrance slit are made through an Ha Halle monochromator. A typical spectrogram and spectroheliogram are shown.” —R. A. Miller, Applied Optics, 4(9), 1085–1089 (1965).

The members of the MO 150th Anniversary Exhibition Committee came from different research programs of the observatory:

  • Dr. Obiminda Cambaliza (Committee Head), Niño Uy and Melliza T. Cruz of UAQ / ITD (Urban Air Quality / Instrumentation Technology Development)
  • Randell G. Teodoro of SED (Solid Earth Dynamics)
  • Dr. Quirino M. Sugon Jr. of UAD (Upper Atmosphere Dynamics)
  • Mariel Templanza of Archives

Yael A. Buencamino, Managing Curator of the Ateneo Art Gallery, served as project consultant.

A. Discoveries (1865–1940)

The first exhibition, Discoveries, showcases the beginnings and rapid growth of the Manila Observatory from 1865 under the Spanish government, and its reorganization under the American administration from 1901 up until World War II.  From its humble beginnings in an abandoned pigeon house, the Meteorological Service of the Philippines known as the Observatorio Meteorológica de Manila was established under the Royal decree issued by the King of Spain in 1884.  The Observatorio was later recognized as the Philippine Weather Bureau after the passage of a bill in 1901 under the American government.  Through the intersection of excellence in scientific research and the Observatory’s mission to serve the community, the Jesuit forefathers made significant contributions in the fields of Meteorology, Seismology, and Astronomy.  (Exhibition Dates: April– June 2015)

B. Transitions (1940-1990)

Transitions Exhibition showcases the rise of the Manila Observatory from the ruins of the Second World War.  After the government decided to establish its own Philippine Weather Bureau run by Filipinos, the Jesuits of the Observatory discerned on its new direction for six long years while waiting for the reconstruction funds from the Philippine War Damage Commission: the Manila Observatory shall focus on seismology and sun-earth relationship. These new research directions were at the frontiers during those times: Russia launched its Sputnik satellite only in 1957 and the Plate Tectonic theory was firmly established only in 1965. (Exhibition Dates: July–August 2015)

C. Frontiers (1990–Present)

The timeline of the Frontiers Exhibition is from 1865 to the present, and will also encompass, in part, our vision for the future.  Since its inception in 1865, the Manila Observatory remained consistent in responding to the needs of the country, making incremental contributions to challenging Science questions that affect our people’s quality of life.  In the 1990’s, with disproportionate use of fossil fuel, climate change is more obvious and became alive in our consciousness as an institution.  We recognized the changing needs of our country, region and also our planet.  Combined with our increasing poverty and population density, this global problem makes us more vulnerable especially in the face of extreme weather events, worsening air pollution, and natural geophysical hazards.  It is in the light of these that the Observatory established its present Science Agenda to address the challenges of sustainable develop- ment and poverty reduction through centers focused on advancing its mission across the following areas: remote sensing and ground-based environmental observations; climate change, variability, and extremes; disaster risk and sustainable development; and public health and human vulnerability.  As a Jesuit scientific research institution, the Manila Observatory remains committed to venture to the scientific peripheries in service of the community.
