California's Drought Improving

California's Drought Improving
Waves of rainfall from Pacific Ocean storms show signs of improving the exceptional drought conditions that have been plaguing California. Starting on about November 30, 2014 storms frequently moved over California. A Multi-satellite Precipitation Analysis (MPA) using data (3B42) archived at near "real time" at the NASA Goddard Space Flight Center was used in the analysis. It indicates that northern California has had far more beneficial rainfall than southern California. This analysis shows that storms dropped over 350mm (almost 14 inches) in an area north of San Francisco. Southern

Validation Network Data Product User’s Guide - Volume 2 (GPM)

Document Description

This document provides a basic set of documentation for the data products available from the GPM Ground Validation System (GVS) Validation Network (VN). In the GPM era the VN performs a direct match-up of GPM’s space-based Dual-frequency Precipitation Radar (DPR) data with ground radar data from the U.S. network of NOAA Weather Surveillance Radar-1988 Doppler (WSR-88D, or “NEXRAD”). Ground radar networks from international partners are also part of the VN.

"Pineapple Express" Brings Heavy Rains, Flooding to U.S. West Coast

"Pineapple Express" Brings Heavy Rains, Flooding to U.S. West Coast
The West Coast, which has been suffering from a strong drought, is finally seeing some much needed relief as a steady stream of storms and rain pour into the coast from the Pacific. The rains began in Washington and Oregon and have now worked their way down the coast to southern California. The weather pattern responsible for all of the rain is known as the "Pineapple Express." The Pineapple Express is known as an atmospheric river. A large, slow-moving low pressure center off of the West Coast taps into tropical moisture originating around the Hawaiian Islands, which is then channeled

2014 PMM Science Team Meeting Summary from the Earth Observer, November 2014

Document Description

This excerpt from the November 2014 edition of The Earth Observer provides a summary of the activities at the PMM Science Team Meeting which took place from August 4 - 7, 2014. The PMM program supports scientific research, algorithm development, and ground-based validation activities for the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) Core Observatory that launched on February 27, 2014.

Deadly Super Typhoon Hagupit Moved Slowly

Deadly Super Typhoon Hagupit Moved Slowly
As of Today, super typhoon Hagupit has been deadly with up to 27 deaths reported but the Philippines has been spared the widespread destruction caused by Super typhoon Haiyan in 2013. Hagupit's (called Ruby in the Philippines) forward motion slowed on December 4, 2014 before reaching the Philippines. After hitting Samar in the eastern Philippines Hagupit's continued slow movement resulted in high rainfall amounts along the typhoon's track. These high rainfall totals meant that flooding occurred frequently along the typhoon's track. When the TRMM satellite flew over on December 8, 2014 at 0132
