GPM Monitors Western Pacific Typhoon IN-FA

GPM Monitors Western Pacific Typhoon IN-FA
On November 18, 2015 at 1533 the GPM core observatory satellite flew directly over a recently formed typhoon called IN-FA that was located near the Equator well to the southeast of Guam. Favorable environmental conditions such as low vertical wind shear and warm sea surface temperatures helped typhoon IN-FA intensify quickly from a tropical depression on November 17 to a typhoon on November 18, 2015. Rainfall from GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments were used to analyze the rainfall around typhoon IN-FA. GPM's DPR found that rain was falling at

India's Deadly Flooding Rains Measured By IMERG

India's Deadly Flooding Rains Measured By IMERG
During the past week extreme rainfall from two unnamed slow moving tropical lows has causing severe flooding in southern India. This flooding has caused the reported deaths of as many as 71 people. The city of Chennai in the state of Tamil Nadu has been hit exceptionally hard with 59 people people killed. NASA's Integrated Multi-satellite Retrievals for GPM (IMERG) combines all data from 12 satellites into a global map of rainfall at half hourly intervals. The rainfall accumulation analysis above was computed from data generated by IMERG during the past week from November 9-16, 2015. An

Tropical Storm Kate Examined By GPM

Tropical Storm Kate Examined By GPM
Kate became the twelfth named tropical cyclone of the of the 2015 Atlantic hurricane season when it formed near the southeastern Bahamas on Sunday November 8, 2015. Kate re-curved toward the northeast and moved harmlessly over the open waters of the Atlantic. Kate's intensity peaked on November 11, 2015 with winds of about 65 kts making it a category one hurricane on the Saffir-Simpson Hurricane. The GPM core observatory satellite flew above Kate on November 11, 2015 at 0926 UTC (4:26 AM EST) capturing data used in these images. Kate's maximum sustained winds were estimated at about 60 kts (69

A brief animated look at the different types of remote sensing techniques that NASA uses to study the Earth. This video discusses why we need remote sensing to study the Earth, and the differences between active and passive remote sensing from satellites. It also gives examples of different types of data NASA satellites collect about the Earth, and some of the applications of that data.

The Olympic Mountain Experiment, or OLYMPEX, is a NASA-led field campaign, which will take place on the Olympic Peninsula of Washington State from November 2015 through February 2016. The goal of the campaign is to collect detailed atmospheric measurements that will be used to evaluate how well rain-observing satellites measure rainfall and snowfall from space.
