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 product is available in ASCII and netCDF-4 formats from April 1, 2013 thru July 1, 2013.

 

GHRC DAAC has published the GPM Ground Validation Southern Appalachian Rain Gauge IPHEx dataset:

http://dx.doi.org/10.5067/GPMGV/IPHEX/GAUGES/DATA301

The GPM Ground Validation Southern Appalachian Rain Gauge IPHEx dataset contains measurements from 45 rain gauges in the region of the Integrated Precipitation and Hydrology Experiment (IPHEx) field campaign. The main goal of IPHEx was to characterize warm season orographic precipitation regimes and hydrologic processes in complex terrain regions, and to contribute to the development, evaluation, and improvement of remote sensing precipitation algorithms in support of the Global Precipitation Meamsurement mission. These Souther Appalachian data are available in ASCII-csv format and cover a time period greater than that of the IPHEx campaign, from January 3, 2008 thru December 31, 2014. Data collection began in 2008 due to the entire network being funded by the NASA Precipitation Measurement Missions (PMM) to make these observations of orographic precipitation in preparation for the IPHEx field campaign.  The data were delivered to GHRC recently by researchers at Duke University.

 

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 site, and these data are available in ASCII-tsv format.

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 was used during OLYMPEX. In addition to reflectivity and Doppler velocity, the data files include aircraft flight information. The CRS was flown on 10 different days between November 10, 2015 and December 10, 2015. Each data file contains one hour of flight measurements during flight in UTC time. Files for this dataset are in netCDF-3 format and readily accessible without the need of specialized software.

GPM Ground Validation UND Citation Navigation Data OLYMPEX:
http://dx.doi.org/10.5067/GPMGV/OLYMPEX/NAV/DATA101

The GPM Ground Validation UND Citation Navigation Data OLYMPEX dataset supplies navigation data collected by the Cessna Citation II aircraft for flights that occurred during November 12, 2015 through December 19, 2015 for the Olympic Mountains Experiment (OLYMPEX) GPM Ground Validation field campaign. This navigation dataset consists of multiple altitude, pressure, temperature, airspeed, and ground speed measurements in ASCII format.
