The Philippine Atmospheric, Geophysical Astronomical Services Administration- Department of Science and Technology (DOST-Pagasa) said that the construction of the Doppler radar in Aparri, Cagayan will start in March this year.
Engr. Leo L. Bunag, Chief of the Northern Luzon PAGASA Regional Services Division said the Doppler radar would make it possible to gauge the rainfall volume and forecast typhoon directions.
At present, Bunag said, the Pag-asa Northern Luzon is still using conventional instruments in the weather forecasts in the area.
Bunag further said, through the Doppler radar, the Pagasa could give more advance warning on the strength, direction and rainfall content of approaching meteorological events and this will enable the residents as well as the concerned agencies to prepare for disasters.
The Doppler radar, a state-of-the-art technology, has four major components – meteorological radar system; meteorological data display system; meteorological data satellite communications system, Very Small Aperture Terminal (VSAT) and a radar building.
Earlier, Bunag said that the Doppler radar in Aparri, Cagayan is one of the Doppler installation projects of DOST-Pag-asa which is a part of the P500 million Japan International Cooperation Agency (JICA) grant to PAGASA.
Aside from the Doppler radar installation, the DOST-Pagasa is also in the process of identifying sites for the establishment of automatic weather stations (AWS). Bunag said the sites for the AWS should be secured because these are usually unmanned.
“ We have already established one AWS in Palanan, Isabela and we intend to establish another in Divilacan and Maconacon in Isabela and Sta. Ana in Cagayan.
The automatic weather stations are sending automatic weather reports to Pagasa through short messaging system or SMS. (TCBicarme)
