GHRSST NOAA/STAR GOES-19 ABI L3C America Region SST v3.0 dataset

The GOES-19 Advanced Baseline Imager (ABI) Level 3C Sea Surface Temperature (SST) dataset, produced by the National Oceanic and Atmospheric Administration (NOAA), provides gridded observations of sea surface temperature derived from satellite-based thermal infrared measurements acquired by the ABI instrument aboard the GOES-19 geostationary satellite. Originally launched as GOES-U on 25 June 2024 and renamed GOES-19 after reaching geostationary orbit, the satellite operates at an altitude of approximately 35,800 km and continuously observes a Full Disk domain spanning approximately 15°W–135°W and 60°S–60°N. The ABI is a 16-band multispectral imager designed to provide enhanced SST retrieval capability through improved radiometric calibration, image navigation, co-registration accuracy, spectral fidelity, and advanced preprocessing.

SST retrievals are derived from thermal infrared observations acquired every 10 minutes and provide near-continuous monitoring of ocean surface thermal conditions across the GOES Full Disk domain. The Level 3C SST product is generated by the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) system from collated Level 2 Preprocessed (L2P) SST retrievals. The Level 3C product provides hourly gridded SST fields on a regular 0.02-degree equal-angle grid and is distributed in netCDF4 format compliant with the GHRSST Data Specification Version 2 (GDS2).
