GHRC DAAC

NASA's Global Hydrology Resource Center (GHRC) published three Global Precipitation Measurement (GPM) Ground Validation Next Generation Weather Radar (NEXRAD) Olympic Mountains Ground Validation Experiment (OLYMPEX) datasets. These NEXRAD OLYMPEX datasets contain data from selected NEXRAD instruments in operation during the OLYMPEX field campaign. NEXRAD is a network of 160 stationary S-Band radars dispersed throughout the United States and select locations abroad. Datasets gathered from three of the NEXRAD stations contain browse images of base reflectivity observations in the Portable Network Graphic (.png) format extending from 22 September 2015 through 01 May 2016 during the OLYMPEX field campaign. Base radar reflectivity is the measure of transmitted power returned to the radar after intercepting a target, such as rain droplets.

NASA's National Snow and Ice Data Center (NSIDC) Distributed Active Archive Center (DAAC) has published the dataset Making Earth System data records for Use in Research Environments (MEaSUREs) Northern Hemisphere Polar Equal-Area Scalable Earth (EASE) Grid 2.0 Daily 6 km Land Freeze/Thaw Status from Advanced Microwave Scanning Radiometer for Earth Observing Systems (AMSR-E) and AMSR2, Version 1. This dataset, part of the MEaSUREs Program, augments an existing global 25 km resolution data set, the MEaSUREs Global Record of Daily Landscape Freeze/Thaw Status. It provides daily landscape Freeze/Thaw status at 6 km resolution for the years 2002 to 2016 derived from observations acquired by the AMSR-E and AMSR2.
NSIDC DAAC has published a correction to the dataset IceBridge Snow Radar L1B Geolocated Radar Echo Strength Profiles, Version 2 for data collected on 19 May 2016. The error affected the calculation of the elevations of the internal layers, as well as the layer thicknesses for that date only. The data for 19 May 2016 have been reprocessed and replaced with the corrected data.

NSIDC DAAC has published a correction to the dataset IceBridge Ku-Band Radar L1B Geolocated Radar Echo Strength Profiles, Version 2 for data collected on 19 May 2016. The error affected the calculation of the elevations of the internal layers, as well as the layer thicknesses for that date only. The data for 19 May 2016 have been reprocessed and replaced with the corrected data.
