    • NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 1b Radiances

    Metadata Updated: November 2, 2023

    The Advanced Baseline Imager (ABI) operates on board the NOAA Geostationary Operational Environmental Satellite-R (GOES-R) Series weather satellites providing advanced imagery and atmospheric measurements of Earth’s Western Hemisphere. The Advanced Baseline Imager (ABI) instrument samples the radiance of the Earth in sixteen spectral bands using several arrays of detectors in the instrument’s focal plane. Single reflective band ABI Level 1b Radiance Products (channels 1 - 6 with approximate center wavelengths 0.47, 0.64, 0.865, 1.378, 1.61, 2.25 microns, respectively) are digital maps of outgoing radiance values at the top of the atmosphere for visible and near-infrared (IR) bands. Single emissive band ABI L1b Radiance Products (channels 7 - 16 with approximate center wavelengths 3.9, 6.185, 6.95, 7.34, 8.5, 9.61, 10.35, 11.2, 12.3, 13.3 microns, respectively) are digital maps of outgoing radiance values at the top of the atmosphere for IR bands. Detector samples are compressed, packetized and down-linked to the ground station as Level 0 data for conversion to calibrated, geo-located pixels (Level 1b Radiance data). The detector samples are decompressed, radiometrically corrected, navigated and resampled onto an invariant output grid, referred to as the ABI fixed grid. There are three spatial coverage scenes per satellite (GOES East and GOES West): Full Disk is the full hemispheric view; Contiguous U.S. is the lower 48 states; and Mesoscale 1 and 2 are for weather event views.
