Abstract. The Geostationary Operational Environmental Satellite (GOES) series is operated by the US National Oceanographic and Atmospheric Administration (NOAA). While in operation since the mid-1970s, the current series (GOES 8–15) has been operational since 1994. This document describes the Gridded Satellite (GridSat) data, which provide GOES data in a modern format. Four steps describe the conversion of original GOES data to GridSat data: (1) temporal resampling to produce files with evenly spaced time steps, (2) spatial remapping to produce evenly spaced gridded data (0.04° latitude), (3) calibrating the original data and storing brightness temperatures for infrared (IR) channels and reflectance for the visible channel, and (4) calculating spatial variability to provide extra information that can help identify clouds. The GridSat data are provided on two separate domains: GridSat-GOES provides hourly data for the Western Hemisphere (spanning the entire GOES domain) and GridSat-CONUS covers the contiguous US (CONUS) every 15min (dataset reference: https://doi.org/10.7289/V5HM56GM).

Short summary
The current Geostationary Operational Environmental Satellite (GOES) 8–15 series has been operational since 1994. Gridded Satellite (GridSat) data provide GOES data in a modern format to simplify access: data have been temporally resampled to regular time intervals, spatially remapped to ~ 4 km spacing, and calibrated. GridSat-CONUS and GridSat-GOES provide data at 15 min and 1 h intervals, respectively. The result is a smaller and easier-to-use dataset.
The current Geostationary Operational Environmental Satellite (GOES) 8–15 series has been...
