As Tropical Depression 11W was strengthening into Tropical Storm Son-tinh near the northern Philippines, the Global Precipitation Measurement mission or GPM core satellite analyzed its rainfall.
As Tropical Depression 11W was strengthening into Tropical Storm Son-tinh near the northern Philippines, the Global Precipitation Measurement mission or GPM core satellite analyzed its rainfall.
TD11W or Son-Tinh, is the first tropical cyclone of 2018 for the northern Philippines, where the storm is known locally as "Tropical Cyclone Henry."
At the time GPM passed overhead, Son-Tinh was still a tropical depression. It was close to the northern Philippines on July 16, 2018 at 4:51 a.m. EDT (0851 UTC). GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.
Data collected by GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments showed that the tropical cyclone was relatively small but was dropping moderate to heavy rain over much of the northern Philippine island of Luzon.
