NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) has published two datasets from the Global Precipitation Measurement Ground Validation (GPM-GV) program.
- GPM-GV Micro Rain Radar (MRR) Olympic Mountain Experiment (OLYMPEX) dataset. This dataset contains measured and derived data from MRR instruments placed in four separate locations within the study region. The MRR is a Biral/Metek 24 GHz (K-band) vertically oriented Frequency Modulated Continuous Wave (FM-CW) radar that measures signal backscatter from which Doppler spectra, radar reflectivity, Doppler velocity, drop size distribution, rain rate, liquid water content, and path integrated attenuation are derived. Data were collected from October 31, 2014 through May 22, 2016, during OLYMPEX.
- GPM-GV United States Department of Agriculture Agricultural Research Service Soil Moisture Iowa Flood Studies (IFloodS) dataset. A total of 15 stations were deployed near the South Fork River in North Central Iowa. The soil moisture probes measure hourly instantaneous measurements of the real dielectric permittivity, soil temperature, bulk electrical conductivity, and volumetric soil moisture. This dataset also consists of precipitation amount, air temperature, relative humidity, vapor pressure, wind speed, wind direction, and solar radiation measurements. Data were collected from April 17, 2013 through June 4, 2013, during the IFloodS Field Experiment.
GHRC DAAC has published the Hurricane and Severe Storm Sentinel (HS3) Scanning High-Resolution Interferometer Sounder (S-HIS) dataset. The S-HIS instrument measures emitted thermal radiances that are used to obtain temperature and water vapor profiles of the Earth's atmosphere in clear-sky conditions. Due to the S-HIS scanning capability, the instrument provides 2 km resolution (at nadir) across a 40 km wide ground swath when flown at an altitude of 20 km aboard NASA's Global Hawk unmanned aircraft. S-HIS data were collected during the 5-week HS3 field campaign study periods in the 2012 to 2014 Atlantic hurricane seasons.

NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) added new data from Special Sensor Microwave Imager / Sounder (SSMIS) data from the F16 platform to the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature Earth System Data Record (ESDR).
Version 1 of the NASA Suomi-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) Snow Cover 6-Min Swath 375m (VNP10) dataset is now available at NSIDC DAAC. The VIIRS snow cover algorithm has been specifically designed to be compatible with Moderate Resolution Imaging Spectroradiometer (MODIS) Terra and Aqua Version 6 snow cover datasets, to ensure continuity between the products and facilitate a climate-data record from the three sensors.
NSIDC DAAC would like to announce a change to data access for the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Annual Greenland Outlet Glacier Terminus Positions from SAR, Version 1 dataset. Data access is now solely through our primary portal at: https://n5eil01u.ecs.nsidc.org/MEASURES/NSIDC-0642.001/. File level spatial and temporal metadata have been added to aid in searching the data.
NSIDC DAAC has also made updated Soil Moisture Active Passive (SMAP) Level-4 Products. There are several changes to the Level 4 soil moisture and carbon data. SMAP observations are now assimilated in Eastern Europe, the Middle East, and East Asia due to expanded coverage of the brightness temperature scaling parameters. An improved version of the model-only Nature Run (NRv4.1) simulation is used to derive the brightness temperature scaling parameters, the model soil moisture initial conditions, and the soil moisture climatology. Level 4 carbon model now uses dynamic 8-day Fraction of Photosynthetically Active Radiation (fPAR) inputs obtained from the latest (Collection 6) Moderate Resolution Imaging Spectroradiometer (MODIS) fPAR record at 500 m resolution.
