EOSDIS Data News: May 4, 2018
NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published the Global Precipitation Mission Ground Validation (GPM-GV) NASA S-Band Dual-Polarimetric (NPOL) Doppler Radar Wallops Flight Facility dataset which consists of rain rate, reflectivity, Doppler velocity, and other radar measurements obtained from the NPOL Doppler radar positioned at NASA's Wallops Flight Facility in support of GPM. NPOL was developed by scientists at Wallops and is a fully transportable and self-contained S-band (10 cm), scanning dual-polarimetric Doppler research radar that was placed near Newark, Maryland in between deployment to GPM GV field campaigns. Data exist for discontinuous time periods ranging from December 6, 2013 thru April 28, 2017. Data files are available in Universal Format (UF), with browse files in PNG format. The browse files contain corrected radar reflectivity, differential reflectivity, specific differential phase, co-polar correlation, and Doppler velocity images. This is a large dataset with files tarred into daily collections zipped for storage and quick download.
NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the Arctic-Boreal Vulnerability Experiment (ABoVE) dataset: Hyperspectral Imagery from the Airborne Visible/Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) for Alaskan and Canadian Arctic, 2017. This dataset provides Level 1 radiance and Level 2 surface reflectance measured by the AVIRIS-NG instrument during flights over the ABoVE domain between June and August 2017. AVIRIS-NG measures reflected radiance at 5-nanometer (nm) intervals in the visible to shortwave infrared spectral range between 380 and 2510 nm. Measurements are radiometrically and geometrically calibrated and provided at approximately 5-meter spatial resolution. The data include 422 flight lines covering areas of interest to the ABoVE campaign over much of Alaska and western Canada.
