NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) released the data set GLDAS Version 2.0 (GLDAS-2.0) Daily Data from the Catchment Land Surface Model (“Catchment-LSM”). This new product has two components. One component is forced entirely with the Global Meteorological Forcing Dataset (hereafter, GLDAS-2.0). The other component is forced with a combination of model- and observation-based forcing data sets (hereafter, GLDAS-2.1). GLDAS-2.0 from Catchment-LSM contains 33 variables (forcing and model outputs) at 0.25º spatial resolution, covering the period from January 1, 1948 to December 30, 2014.
NASA's Global Hydrology Resource Center (GHRC) Distributed Active Archive Center (DAAC) recently published the GPM Ground Validation CAX1 Radar CFradial format OLYMPEX dataset. This dataset was collected by the dual polarization X-band “CAX1” portable scanning radar during the GPM Ground Validation Olympic Mountains Experiment (OLYMPEX) field campaign that took place in the Pacific Northwest during November 2015 through April 2016. The dataset consists of radar parameters such as radar reflectivity, Doppler velocity, Doppler width, differential reflectivity, and signal quality indices provided at a 0.4 to 1.0 km spatial resolution. The CAX1 radar was operated by Environment and Climate Change Canada and located at the southern tip of Vancouver Island on the Canadian Forces Base Esquimalt Albert Head (AHD) military training area. The data files are available in Cfradial netCDF-4 format.
GHRC DAAC has published the GPM Ground Validation Iowa Flood Center (IFC) NEXRAD Composite IFloodS dataset. This dataset contains rain rate estimates derived using NEXt Generation Weather RADar system (NEXRAD) radars in operation during the Iowa Flood Studies (IFloodS) field campaign carried out to support Global Precipitation Measurement (GPM) ground validation. NEXRAD is a network of 160 stationary S-Band radars dispersed throughout the United States and select locations abroad. Data from NEXRAD radars within and near the IFloodS Iowa study region were gathered during April 19, 2013 through June 30, 2013 to create this subset for IFloodS support. The NEXRAD Composite data files are available in netCDF-4 or ASCII format with associated reflectivity browse imagery available in GIF format.
VIIRS swath data customization options are now available at NASA's National Snow and Ice Data Center (NSIDC) DAAC. VIIRS 6-minute swath (VNP10, VNP29, & VNP30) datasets use algorithms specifically designed to be compatible with Moderate Resolution Imaging Spectroradiometer (MODIS) Terra and Aqua Version 6 datasets. In addition, data customization options for VIIRS are similar to MODIS and include subsetting, reformatting, and reprojection. These options are provided by NASA Earthdata Search or can also be accessed programmatically.
NSIDC DAAC has published Version 2 of the MEaSUREs MODIS Mosaic of Greenland (MOG) 2005, 2010, and 2015 Image Maps data set. Version 2 includes Mosaic of Greenland 2010 and 2015 (MOG2010 and MOG2015) data, in addition to the MOG2005 data. This data set is funded by NASA’s Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
NSIDC DAAC has published field data from the Soil Moisture Active Passive Validation Experiment 2015 (SMAPVEX15) validation campaign. The new data set contains in situ gravimetric and volumetric soil moisture, bulk density, and soil temperature measurements. Visit the product page for details.
NSIDC DAAC has published the SnowEx17 Cloud Absorption Radiometer BRDF, Version 1 data set. This data set contains measurements of the bidirectional reflectance distribution function (BRDF) at two locations in Colorado—Grand Mesa, a snow-covered, forested study site about 40 miles east of Grand Junction, and Senator Beck Basin approximately 80 miles to the SSE of Grand Mesa. These data were obtained during the NASA SnowEx 2017 campaign using the Cloud Absorption Radiometer, an airborne multi-angular, multi-wavelength scanning radiometer that measures scattered light in 14 spectral bands.
NSIDC DAAC has published data from January 2018 for the MEaSUREs Greenland Image Mosaics from Sentinel-1A and 1B, Version 2 data set. This data set is part of the Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program.
NASA's Oak Ridge National Laboratory (ORNL) DAAC published the Soil Collection dataset Global Hydrologic Soil Groups (HYSOGs250m) for Curve Number-Based Runoff Modeling. This dataset represents a globally consistent, gridded dataset of hydrologic soil groups (HSGs) with a geographical resolution of 1/480 decimal degrees, corresponding to a projected resolution of approximately 250-m.
