2 OUTLINE Introduction Recent Developments in Observational Network TRMM Application/Utilization Summary/Recommendations

3 Background Information Geographical Information

4 Earth Observation Systems in the Philippines Atmosphere The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) under the Department of Science and Technology (DOST) is the National Meteorological Service. The Philippines, through the PAGASA, is a Member of the World Meteorological Organization (WMO), a specialized body of the United Nations

5 Meteorological Observation Systems in the Philippines The PAGASA-DOST Maintains network of information consisting of: - 58 surface weather stations - 21 agrometeorological observation stations - 4 upper-air stations - 5 weather surveillance radars - 17 aeronautical meteorological stations - 2 satellite ground receiving system - 2 WEFAX satellite receiving system rain/climat stations -2 DCPs

6 PAGASA s Observational Network: Recent Developments Upgraded the Polar Orbiting Meteorological Satellite Station Upgraded the Geostationary Meteorological Receiving Station for MTSAT 1R for Manila and Cebu in Central Philippines Acquired local funding for the installation of MODIS Receiving Station Rehabilitated/Upgraded 5 Weather Surveillance Radars Acquired local funding for the installation of 5 Doppler Radars Upgraded 3 Upper-air stations

7 PAGASA s Observational Network - Rehabilitated 5 RADARS Weather Surveillance Radars

12 TRMM Application/Utilization Tropical cyclone rainfall Extreme rainfall events Climatological applications

13 Data used Tracks of tropical cyclones that entered the PAR during the period tropical cyclones

14 Average tropical cyclone tracks 4 th Qtr

15 Annual frequency of T.C. entering the PAR and crossing the Philippines ( ) Annual Number of Tropical Cyclones inside the PAR Crossing and not crossing the Philippines 35 Number of Tropical Cyclones Year TC's which crossed/landfall TC's inside PAR but didn't cross/landfall Annual Average no. entering PAR = 20 Average crossing = 9 T.C.

18 WHY TRMM IS VALUABLE? The TRMM satellite will provide unique information about the structure and evolution of hurricanes or tropical cyclones. The TRMM satellite carries a Precipitation Radar, the first instrument that can accurately detect and measure rain over land from space.

21 Typhoon MARCE

22 EXTREME RAINFALL EVENTS The large-scale landslide occurred on February 17 was triggered by the heavy rain. The town of Guinsaugon was buried by the landslide and lost about 1,000 lives. This is the image which was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer(ASTER) in the Leyte island southeast region on March 1, 2006 after this disaster. The landslide was about 800m in width and about 3.5km in length.

27 Summary/Recommendations TRMM provide accurate estimates of rainfall from tropical cyclones and extreme rainfall events. There are limitations however, particularly on the frequency of data availability. We need more TRMM GPM
