The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Autonomous Parsivel Unit (APU) Wallops Flight Facility (WFF) dataset. This dataset consists of precipitation data including precipitation amount, precipitation rate, reflectivity in Rayleigh regime, liquid water content, drop diameter, and drop concentration obtained from six Autonomous Parsivel Units (APUs) positioned at the Wallops Flight Facility (WFF) in support of the Global Precipitation Mission (GPM). The APU is an optical laser-disdrometer based on single particle extinction that measures particle size and fall velocity. It consists of the Parsivel2 developed by OTT in Germany and supporting hardware developed by University of Alabama. Data are available in ASCII format for the period of May 6, 2013 through October 9, 2014.GHRC News

The NASA Global Hydrology Resource Center (GHRC) DAAC published the GPM Ground Validation Weather Research and Forecasting (WRF) Images MC3E dataset. This data consists of browse only images showing radar reflectivity, radar echo top, convective available potential energy (CAPE), temperature, geopotential height, wind speed, relative humidity, rain water, snow, cloud water, cloud ice, and graupel. These data were simulated by the Weather Research and Forecasting (WRF) for the period of the GPM Ground Validation Mid-latitude Continental Convective Cloud Experiment (MC3E) field campaign. The overarching goal of the MC3E field campaign was to provide the most complete characterization of convective cloud systems, precipitation, and the environment ever obtained and to provide new constraints for model cumulus parameterizations and space-based rainfall retrieval algorithms over land. Browse imagery files in PNG and GIF formats are available for April 19, 2011 through June 6, 2011.
GHRC DAAC held its annual User Working Group meeting November 13-14 in Huntsville, AL. The primary focus of this meeting was to present GHRC FY2018 successes and provide descriptions of FY2019 goals. The DAAC also reported improvements and changes that directly responded to last year's UWG recommendations. The GHRC DAAC UWG was led by chairs Michael Peterson (Los Alamos National Laboratory) and Pierre Kirstetter (University of Oklahoma). We were also pleased to have several guests joining us, including Andy Mitchell, Drew Kittel and Steve Berrick from NASA's Earth Science Data and Information Systems (ESDIS) Project; Bruce Wilson (ORNL DAAC) and Chris Doescher (LP DAAC). A lively afternoon brainstorming session included topics on how to broaden the GHRC user base, improve field campaign data use, and future communication with our users.
The NASA Global Hydrology Resource Center (GHRC) DAAC published a new Micro Article about the Integrated Precipitation and Hydrology Experiment (IPHEx) Field Campaign. A Micro Article is a short, interesting document that brings together data and key science concepts. The IPHEx field campaign was a Global Precipitation Measurement (GPM) Ground Validation field campaign that consisted of a wide variety of ground instrumentation, radars, and multiple aircrafts to gain further understanding of how mountainous areas influence and interact with summertime precipitation before, during, and after rainfall occurs. The intensive observing period took place from May 5, 2014 through July 15, 2014.

GHRC User Working Group member Michael Peterson creates lightning videos taken from data from the Geostationary Lightning Mapper (GLM) on the GOES-16 spacecraft and the Lightning Imaging Sensor on the International Space Station (ISS LIS). These videos recently showed the lightning in Hurricane Florence during its track across the Atlantic and as it made landfall. He has created CONUS videos in 3 different speeds, a full disk video, and a 360 degree video of the hurricane showing the lightning flashes.
Here are some locations of these videos:
