The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Filipino: Pangasiwaan ng Pilipinas sa Serbisyong Atmosperiko, Heopisiko at Astronomiko, [4] abbreviated as PAGASA, which means "hope" as in the Tagalog word pag-asa) is the National Meteorological and Hydrological Services (NMHS) agency of the Philippines mandated to provide protection against natural calamities ...
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
A Doppler weather radar monitoring tower in the town operated by the Philippine Atmospheric, Geophysical and Astronomical Services Administration was assessed as "structurally unsafe" after sustaining large cracks [34] and was further sealed off due to its vulnerability to liquefaction. [35]
Local Development of Doppler Radar Systems (LaDDeRS) – to develop local capacity to operate Doppler weather radar systems. Landslide Sensors Development Project – a low-cost, locally developed, sensor-based early monitoring and warning system for landslides, slope failures, and debris flow.
Once the radar can "look down", it is subsequently desirable to "shoot down". Various weapons systems (including guns and missiles) are then employed against designated radar targets, either relying on the aircraft's radar employing the "look down" capability (as in semi-active radar homing) or the weapon's own active radar to resolve the indicated target (as in active radar homing).
Typhoon Krathon, known in the Philippines as Super Typhoon Julian, was a powerful and erratic tropical cyclone which impacted Taiwan and the Philippines in late September and early October 2024. Krathon, which refers to the santol fruit, was the first storm to make landfall on Taiwan's densely populated western plains since Typhoon Thelma in 1977.
A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS [7] is active, which adds a supplemental low-level scan while completing a volume scan ...
