3B4xRT Reduced Volume of Data

Starting about 22:00 UTC on 20 October 2014 PPS started having issues with missing input data files originating at NOAA. Informally we have been told that there is a major network issue, but have no insight on its nature or likely duration. Until this is resolved, the input data for the 3B4xRT suite of products will suffer greatly reduced volume. Currently, we are not receiving sounder data, and the IR fields only have GOES-E and -W.

GPM Measures Rainfall In Tropical Storm Adjali

Moderate rainfall was occurring around the center of Tropical Storm Adjali before it dissipated, according to data from NASA and the Japan Aerospace Exploration Agency's Global Precipitation Measurement or GPM satellites. Adjali became the first named storm of the Southwest Indian Ocean 2014/2015 cyclone season when it formed on November 16, 2014. Adjali became a strong tropical storm the next day and just two days later started to dissipate. The GPM observatory captured data on Adjali's rainfall rates on Nov. 18. GPM's Microwave Imager (GMI) instrument is similar to the Tropical Rainfall

Document Description

The transition from the Tropical Rainfall Measuring Mission (TRMM) data products to the Global Precipitation Measurement (GPM) mission products has begun. This document specifically addresses the multi-satellite products, the TRMM Multi-satellite Precipitation Analysis (TMPA), the real-time TMPA (TMPA-RT), and the Integrated Multi-satellitE Retrievals for GPM (IMERG).

Hurricane Vance Weakening, Heading Toward Mexico

The TRMM satellite flew over hurricane Vance on November 2014 at 0953 UTC. Rainfall derived from TRMM's Microwave Imager (TMI) data collected with that view are shown overlaid on a 1000 UTC GOES-WEST image. This analysis showed that Vance had a large area of heavy rainfall near the center of the hurricane. Some intense storms in that area were dropping rain at a rate of over 50mm/hr (almost 2 inches) per hour. Vance's power peaked late on November 3, 2014 with winds of about 95 kts (about 109 mph). Vertical wind shear had started to weaken the hurricane at the time of this view but Vance was

Tropical Storm Vance Forms

The hurricane season continues to be active in the eastern Pacific Ocean. A Tropical depression south of southern Mexico was upgraded to tropical storm Vance yesterday. The National Hurricane Center (NHC) predicts that Vance will become a hurricane Sunday morning making it the sixteenth hurricane of the 2014 eastern Pacific Ocean hurricane season. TRMM's Microwave imager (TMI) had a good view of the rainfall around tropical storm Vance on October 31, 2014 at 0234 UTC. An analysis of this rainfall is shown overlaid on a 0245 UTC GOES-EAST enhanced infrared image. Intense convective
