The NASA Making Earth System Data Records for Use in Research (MEaSUREs) Greenland Image Mosaics from Sentinel-1A and -1B dataset available at NASA's National Snow and Ice Data Center Distributed Active Archive Center ( NSIDC DAAC), has been updated with mosaics through February 2019. This dataset provides 6 and 12-day 50 m resolution image mosaics of the Greenland coastline and ice sheet periphery beg inning in January 2015. The mosaics are derived from C-band Synthetic Aperture Radar (C-SAR) acquired by the Copernicus Sentinel-1A and -1B imaging satellites. Discover and access these data: https://bit.ly/2Vr5aGc

NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) has released the GPM Ground Validation Radiosonde LPVEx dataset consisting of sounding data collected as part of the Global Precipitation Measurement ( GPM) mission Ground Validation Light Precipitation Validation Experiment ( LPVEx). This field campaign took place around the Gulf of Finland in September and October of 2010. The goal of the campaign was to provide additional high altitude, light rainfall measurements for the improvement of GPM satellite precipitation algorithms. The Vaisala RS92 radiosonde was used to produce vertical profiles of atmospheric temperature, pressure, humidity, and winds. The radiosondes were launched from two locations: Kumpula and Vantaa.
