CER_GEO_Ed4_GOE18_NH_V01.4 is the Satellite ClOud and Radiation Property retrieval System (SatCORPS) Clouds and the Earth's Radiant Energy System (CERES) Geostationary Satellite (GEO) Edition 4 Geostationary Operational Environmental Satellite 18 (GOES-18) over the Northern Hemisphere (NH) Version 1.4 data product. Data was collected using the Advanced Baseline Imager (ABI) on the GOES-18 Platform. Note: Version 1.4 uses the Global Modeling and Assimilation Office (GMAO) Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) reanalysis for atmospheric input; Version 1.2 used GMAO's GEOS-5.4.1. No changes have been made to the cloud retrieval algorithm. This data set is comprised of cloud micro-physical and radiation properties derived hourly from GOES-18 geostationary satellite imager data using the Langley Research Center (LaRC) SATCORPS algorithms in support of the CERES project. The data set is arranged as files for each hour in netCDF-4 format. The observations are at 2-km resolution (at nadir) and are sub-sampled to 6 km (taking every third line and pixel).
