Abstract
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 15 min (dataset reference: https://doi.org/10.7289/V5HM56GM).
Highlights
The National Oceanographic and Atmospheric Administration (NOAA) has used the Geostationary Operational Environmental Satellite (GOES) series since 1975 to monitor weather and other environmental conditions
Gridded Satellite (GridSat)-GOES and GridSat-contiguous US (CONUS) are most similar to two other datasets: the globally merged IR dataset (Janowiak et al, 2001) and the GridSat-B1 Climate Data Record (CDR) (Knapp et al, 2011)
The effort to produce GridSat data required processing GOES area files retrieved from NOAA CLASS (Comprehensive Large Array-data Stewardship System)
Summary
The National Oceanographic and Atmospheric Administration (NOAA) has used the Geostationary Operational Environmental Satellite (GOES) series since 1975 to monitor weather and other environmental conditions. While the series name has remained the same, the satellites providing the data have seen stepwise increases in capabilities. The system received a significant upgrade in 1994 with the launch of GOES 8 (the GOES-I to GOES-M series), providing a five-channel imager (Menzel and Purdom, 1994). The recent launch (in 2016) of GOES 16 is another substantial increase in capabilities (Schmit et al, 2017). The satellites have been maintained at two primary locations: GOES West near 135◦ W, which observes the Eastern Pacific and western North America, and GOES East near 75◦ W, providing coverage of North and South America and much of the Atlantic Ocean. GridSat-CONUS and an hourly domain that spans the Western Hemisphere to cover the entire GOES domain, called GridSat-GOES. We use the term GridSatGOES to describe both these datasets, since their only difference is the temporal resolution and spatial coverage
