GHRSST NOAA/STAR GOES-19 ABI L2P America Region SST v3.0 dataset

Published by DOC/NOAA/NESDIS/STAR;NASA/JPL/PODAAC | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 01:32 PM | Dataset Last Updated: June 23, 2026
The GOES-19 Advanced Baseline Imager (ABI) Level 2 Preprocessed (L2P) Sea Surface Temperature (SST) dataset, produced by the National Oceanic and Atmospheric Administration (NOAA), is used to observe sea surface temperature using satellite remote sensing measurements from the Advanced Baseline Imager (ABI) aboard the GOES-19 geostationary satellite. Originally launched as GOES-U on 25 June 2024 and renamed GOES-19 upon reaching geostationary orbit, the satellite operates at an altitude of approximately 35,800 km and provides continuous observations across the Full Disk domain spanning approximately 15°W–135°W and 60°S–60°N. The ABI instrument is a 16-band multispectral imager that provides enhanced SST retrieval capability through improved radiometric calibration, image navigation, co-registration accuracy, spectral fidelity, and advanced preprocessing. SST retrievals are generated primarily from four thermal infrared channels centered at 8.4, 10.3, 11.2, and 12.3 μm, providing observations every 10 minutes at approximately 2 km spatial resolution at nadir, degrading toward the edge of the viewing domain. This Level 2 Preprocessed SST product contains hourly collated sea surface temperature retrievals generated from 10-minute Full Disk ABI observations using the NOAA Advanced Clear-Sky Processor for Ocean (ACSPO) system. SST retrievals are produced using the ACSPO clear-sky mask and Non-Linear Sea Surface Temperature (NLSST) algorithm and are reported only for clear-sky water pixels, with fill values elsewhere. In addition to SST, the dataset includes brightness temperatures from ABI thermal infrared bands 11, 13, 14, and 15; reflectances from visible and near-infrared bands 2 and 3 used for cloud detection; sun-sensor geometry parameters; quality-control flags indicating day/night, land, ice, twilight, and sunglint conditions; Numerical Weather Prediction wind speed fields from NCEP; and SST departures from the Canadian Meteorological Centre 0.1° Level 4 SST analysis. Per-pixel Sensor-Specific Error Statistics (SSES) bias and standard deviation layers are also provided. The dataset is distributed as 24 hourly granules per day in netCDF4 format compliant with the GHRSST Data Specification Version 2 (GDS2), with an approximate daily volume of 0.6 GB. Ancillary data used in processing include NOAA iQuam quality-controlled in situ SST observations for algorithm tuning and reference analyses for quality assessment. Spatial resolution is approximately 2 km at nadir, degrading to approximately 15 km at a viewing zenith angle of 67°. Users should note that geolocation coordinates are not stored within individual granules and must be obtained separately through companion navigation files or software utilities. The GOES-19 ABI SST product is developed and operated by NOAA and forms part of the ACSPO satellite SST processing system. Product performance is continuously monitored through comparisons with in situ observations using the Satellite Quality Monitor (SQUAM) system, while ABI brightness temperatures are evaluated against radiative transfer model simulations using the MICROS framework. The dataset supports applications including weather forecasting, ocean monitoring, climate studies, marine operations, coastal management, and SST data assimilation. Users should periodically consult product documentation for updates regarding algorithm changes, validation results, and known issues. A companion Level 3 Collated (L3C) gridded SST product at 0.02° spatial resolution is also available for users requiring reduced data volume and regularly gridded SST fields.
