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 files are available from 06 November 2015 to 15 January 2016 in the netCDF-4 file format. There is 1 radar volume per file representing 10 minutes of data.

GHRC DAAC has published three more OLYMPEx datasets:

The GPM Ground Validation Cloud Physics Lidar (CPL) OLYMPEX dataset (image shown) consists of extinction profiles, layer optical depth, layer lidar ratio, and aircraft parameter measurements measured by the CPL flown on the NASA ER-2 aircraft during the Global Precipitation Mission (GPM) Olympic Mountains Experiment (OLYMPEX) campaign. http://dx.doi.org/10.5067/GPMGV/OLYMPEX/CPL/DATA101

The GPM Ground Validation Advanced Vertical Atmospheric Profiling System (AVAPS) OLYMPEX dataset contains dropsonde vertical profiles of atmospheric pressure, air temperature, dew point temperature, relative humidity, wind direction and magnitude, and sensor location obtained during the Olympic Mountains Experiment (OLYMPEX). http://dx.doi.org/10.5067/GPMGV/OLYMPEX/AVAPS/DATA101

The GPM Ground Validation NASA ER-2 Navigation Data OLYMPEX dataset supplies navigation data collected by the NASA ER-2 aircraft for flights that occurred during November 9, 2015 through December 15, 2015 for OLYMPEX. This navigation dataset consists of multiple altitude, pressure, temperature parameters, airspeed, and ground speed measurements in ASCII, ASCII-IWG1, and XML data file formats. http://dx.doi.org/10.5067/GPMGV/OLYMPEX/NAV/DATA201

Global Hydrology Resource Center DAAC has just published the GPM-GV OLYMPEX AMPR dataset at http://dx.doi.org/10.5067/GPMGV/OLYMPEX/AMPR/DATA101.

The GPM Ground Validation Advanced Microwave Precipitation Radiometer (AMPR) OLYMPEX dataset was collected by the AMPR instrument flown on the high altitude ER-2 research aircraft from November 9 - December 15, 2015, during the OLYMPEX - Olympic Mountain Experiment field campaign conducted at Washington State’s Olympic Peninsula. AMPR data at the GHRC DAAC include netCDF format data files of brightness temperature and PNG browse files of Quality Control Flags and Brightness Temperatures.
