The GPM Ground Validation Daily Precipitation OLYMPEX dataset is now available

http://dx.doi.org/10.5067/GPMGV/OLYMPEX/MULTIPLE/DATA301

The GPM Ground Validation Daily Precipitation Olympic Mountain Experiment (OLYMPEX) dataset consists of a single netCDF-4 data file containing estimates of daily precipitation, both rainfall and snowfall amounts, on a 1/32 degree spatial resolution grid covering the extent of the OLYMPEX field campaign region in the Olympic Mountains of the state of Washington. This data product was created for the GPM Ground Validation OLYMPEX field campaign. These VIC precipitation estimates are based on NOAA WSR-88D...

GHRC DAAC is now offering the GPM Ground Validation Duke Soil Moisture IPHEx dataset: http://dx.doi.org/10.5067/GPMGV/IPHEX/GAUGES/DATA102

The GPM Ground Validation Duke Soil Moisture dataset consists of a collection of various data obtained during the Integrated Precipitation and Hydrology Experiment (IPHEx) which occurred in the Southern Appalachians, spanning into the Piedmont and Coastal Plain regions of North Carolina from February 27, 2014 through October 17, 2014. The various instruments used included Theta Probes, Infrared Thermometers, 200-A Soil Core Samplers, a Global Positioning System (GPS), Soil Thermometers with Scanning L-band Active Passive (SLAP) flight concurrent...

GHRC DAAC has published the IFC Stream Flow IFloodS dataset: http://dx.doi.org/10.5067/GPMGV/IFLOODS/GAUGES/DATA201

The GPM Ground Validation Iowa Flood Center (IFC) Stream Flow IFloodS dataset was obtained from the IFC during the Iowa Flood Studies (IFloodS) field campaign that extended from March 31, 2013 through June 30, 2013. The main goal of IFloodS was to evaluate how well the GPM satellite rainfall data can be used for flood forecasting. The IFC monitors stage levels using sensors attached to the side of bridges throughout Iowa. The sensor data are downloaded from the Iowa Flood Information System (IFIS) as support data for the IFloodS campaign. The IFC Stream Flow data were...

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...

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...

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...
