CERES GEO Edition 4 Version 1.4 Collections Announcement

Feb. 5, 2026, 12:23 p.m.

Project: CERES

Version 1.4 of the Satellite Cloud and Radiation Property retrieval System (SatCORPS) Clouds and the Earth's Radiant Energy System (CERES) Geostationary Satellite (GEO) Edition 4 are now available. These datasets, hosted by the NASA Langley Research Center’s Atmospheric Science Data Center (ASDC), provide critical observations of cloud properties and Earth's energy dynamics and are key resources for climate research and modeling applications.

Background 

The data for these collections were collected over the Northern Hemisphere (NH) and over the Southern Hemisphere (SH) from various platforms. First is the Geostationary Operational Environmental Satellites (GOES) using the Advanced Baseline Imager (ABI) on GOES-16, GOES-17, GOES-18 and GOES-19. These observations were at a 2 km resolution at nadir and were sub-sampled to 6 km that took every third line and pixel. GOES-15 used the GOES-15 Imager where the observations were at a 4 km resolution at nadir and were sub-sampled at 8km that took every other line and pixel. Onboard the Himawari Geostationary Satellites (Himawari-8 and Himawari-9) the Advanced Himawari Imager (AHI) was used to collect data. These observations were at a 2 km resolution at nadir and were sub-sampled to 6 km that took every third line and pixel. Data was collected on Meteosat Geostationary Satellites (Meteosat-8 to Meteosat-11) using the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument. These observations were at a 3 km resolution at nadir and were sub-sampled to 6 km that took every other line and pixel.

Data Products 

The collections included in this release are from the following platforms:

Geostationary Operational Environmental Satellites:

Himawari Geostationary Satellites

Meteosat Geostationary Satellites 

Technical Details 

All datasets are arranged as files for each hour in netCDF-4 format while using the Langley Research Center (LaRC) SATCORPS algorithms supporting the CERES project. The 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.
