DPR Ka Radar Data Acquisition has been Restored JacobAdmin Fri, 06/26/2020
Following a reset of the DPR to Standby Mode that occurred on April 22, 2020, the DPR Ka radar data acquisition has been restored. PPS is releasing the DPR and downstream data for distribution from April 22, 2020 - April 30, 2020. There are continuing short data outages for the radar that are being investigated and corrective measures are scheduled to be applied on May 14, 2020. PPS will be releasing May 2020 data in stages with an expected return to normal data availability soon after the corrective measures are applied. For Level-1 and Level-2 products, users should check the dataQuality
GPM observes Hurricane Dorian lashing Florida
Download in high resolution from the NASA Goddard Scientific Visualization Studio GPM captured Dorian at 10:41 UTC (6:41 am EDT) on the 4th of September when the storm was moving north-northwest parallel to the coast of Florida about 90 miles due east of Daytona Beach. Three days earlier, Dorian had struck the northern Bahamas as one of the most powerful Category 5 hurricanes on record in the Atlantic with sustained winds of 185 mph. Weakening steering currents allowed the powerful storm to ravage the northern Bahamas for 2 full days. During this time, Dorian began to weaken due to its...
GPM Observes Hurricane Dorian Over Bahamas
Download in high resolution from the NASA Goddard Scientific Visualization Studio. The NASA / JAXA Global Precipitation Measurement (GPM) Core Observatory flew over Hurricane Dorian on September 1st (5:22pm ET / 21:22 UTC) as the storm was directly over Abaco Island in The Bahamas. The satellite captured data on rainfall rates within the storm as it flew over using its Dual-frequency Precipitation Radar (DPR) and GPM Microwave Imager (GMI). In this animation the multi-satellite GPM IMERG product is shown first to illustrate rainfall rates prior to the overpass. When the camera zooms in data...

Document Description

This document describes the basic idea of DPR data processing. It was originally written for the
algorithm used in the at-launch version (V03). The algorithm has been modi ed and improved
since then. Although the basic idea of data processing remains the same, the actual ow of
processing, in particular that in the solver module, has changed substantially. As a result, some
part of description in section 3.1 may not be relevant any more.

Changes in the DPR algorithm from V05 to V06

Dive Into a 360-View of Hurricane Maria
Two days before Hurricane Maria devastated Puerto Rico, the NASA/JAXA Global Precipitation Measurement Core Observatory satellite captured a 3D view of the 2017 storm. At the time Maria was a category 1 hurricane. The 3-D view reveals the processes inside the hurricane that would fuel the storm’s intensification to a category 5 storm within 24 hours. For the first time in 360 degrees, this data visualization takes you inside the hurricane. The precipitation satellite has an advanced radar that measures both liquid and frozen water. The brightly colored dots show areas of rainfall, where green...

GPM Gets Flake-y
In this video GPM Project Scientist Dr. Gail Skofronick-Jackson explains how scientists can measure the size, shape and distribution of snow particles, layer by layer, in a storm using GPM. The Global Precipitation Measurement mission is an international satellite project that provides next-generation observations of rain and snow worldwide every three hours.
