NASA's Global Hydrology Resource Center (GHRC) Distributed Active Archive Center (DAAC) published the Global Precipitation Measurement (GPM) Ground Validation Doppler on Wheels (DOW) Olympic Peninsula during the Olympic Mountain Experiment (OLYMPEX) dataset. This dataset contains radar reflectivity data from a dual-polarization, dual-frequency X-band mobile radar operated by the Center for Severe Weather Research (CSWR). The Doppler on Wheels radar operates on a truck that was located at the edge of Lake Quinault in the Chehalis Valley of the OLYMPEX campaign. The goal of the OLYMPEX field campaign was to collect observations to improve understanding of 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 published the GPM Ground Validation NASA ER-2 Navigation Data OLYMPEX dataset. This dataset supplies navigation data collected by the high-flying NASA ER-2 aircraft for flights that occurred during November 9, 2015 through December 15, 2015 during the Olympic Mountains Experiment (OLYMPEX) GPM Ground Validation field campaign. This ER-2 navigation dataset consists of multiple altitude, pressure, temperature parameters, airspeed, and ground speed measurements in ASCII, ASCII-IWG1, and XML data file formats.
NASA's National Snow and Ice Data Center (NSIDC) DAAC published additional campaign data through 18 November 2016 for the dataset NASA IceBridge Ku-Band Radar L1B Geolocated Radar Echo Strength.
NSIDC DAAC published additional campaign data through 18 November 2016 for the dataset NASA IceBridge Snow Radar L1B Geolocated Radar Echo Strength.
NSIDC DAAC published the beta version of the dataset SMAP/Sentinel-1 L2 Radiometer/Radar 30-Second Scene 3 km EASE-Grid Soil Moisture. L-band radiometer measurements from the SMAP satellite and C-band radar measurements from the European Space Agency (ESA) Copernicus Sentinel-1 satellite are combined to produce high-resolution soil moisture estimates.
NSIDC DAAC published the SMAP Science Data System (SDS) began forward processing for the data on 27 October 2017. Data reprocessing from 01 April 2015 to 27 October 2017 will start in mid-November 2017. The data will be made available as they are processed, and registered users will be notified when reprocessing is complete. These beta-quality data use preliminary algorithms that are still being validated and are therefore subject to uncertainties. The calibrated/validated release of this data set is expected to occur in Spring 2018.
NSIDC DAAC published the dataset Greenland Annual Accumulation along the EGIG Line, 1959–2004, from Airborne Radar and Neutron Probe Densities. This dataset reports mean annual snow accumulation rates (meters water equivalent) at 3 meter intervals along a 250-km segment of the Expéditions Glaciologiques Internationales au Groenland (EGIG) line. Accumulation rates are derived from Airborne SAR/Interferometric Radar Altimeter System (ASIRAS) data and high-resolution neutron-probe density profiles.
NASA's Socioeconomic Data and Applications Center (SEDAC) released the Global Man-made Impervious Surface (GMIS) and Human Built-up and Settlement Extent (HBASE) data sets and the accompanying data visualization and access app for beta testing on 30 October. These data were developed by E. Brown de Coulston from GSFC and colleagues with support from the NASA Land Cover and Land Use Change (LCLUC) Program. The data were derived primarily from the Global Land Survey (GLS) Landsat dataset for the target year 2010.
