GHRC published the GPM Ground Validation Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks Cloud Classification System (PERSIANN-CCS) IFloodS dataset: http://dx.doi.org/10.5067/GPMGV/IFLOODS/PERSIANN/DATA101

This dataset is a subset from the global 30-minute PERSIANN-CCS files generated in near-real time selected for the time period of the GPM Ground Validation Iowa Flood Studies (IFloodS) field campaign. The main goal of IFloodS were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from satellites passing overhead. This PERSIANN-CCS data...

GHRC DAAC just published the GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) OLYMPEX dataset: http://dx.doi.org/10.5067/GPMGV/OLYMPEX/2DVD/DATA/301

The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) OLYMPEX data were collected during the GPM Ground Validation Olympic Mountain Experiment (OLYMPEX) held on the Olympic Peninsula in the Pacific Northwest of the United States. Collected from four sites, the data contains daily ASCII-tsv files with information on individual hydrometeors including the number of hydrometeors, raindrop size distribution, and particle concentration. The data range from October 31, 2015 through January 17, 2016; exact dates may vary per...

GHRC DAAC has published the GPM Ground Validation Cloud Radar System (CRS) OLYMPEX dataset: 
http://dx.doi.org/10.5067/GPMGV/OLYMPEX/CRS/DATA101

The GPM Ground Validation Cloud Radar System (CRS) OLYMPEX dataset provides radar reflectivity and Doppler velocity data collected during the Olympic Mountain Experiment (OLYMPEX). This dataset is used to estimate cloud droplet distribution for the storms monitored during the field campaign. The CRS instrument is a 94GHz W-band Doppler radar with a 3mm wavelength. CRS can be deployed as both an airborne instrument onboard NASA’s high-altitude science aircraft, the Earth Resource 2 (ER-2), as well as a ground based radar system. Only the airborne mode...

GHRC DAAC has published the GPM Ground Validation Doppler on Wheels (DOW) OLYMPEX dataset: http://dx.doi.org/10.5067/GPMGV/OLYMPEX/DOW/DATA101

The GPM Ground Validation Doppler on Wheels (DOW) OLYMPEX dataset was obtained by a dual-polarization and dual-frequency X-band mobile radar operated by the Center for Severe Weather Research (CSWR) during the Olympic Mountain Experiment (OLYMPEX) campaign. The DOW was deployed in the Chehalis Valley for the OLYMPEX field campaign with the goal of obtaining radar reflectivity observations of precipitation in order to better understand the orographic enhancement of precipitation during frontal passages over mountain ranges. The DOW radar uses two 250 kW transmitters with a measurement range of roughly 60 km. CF-Radial data...
