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

ABI-L1b-Rad

browse graphicExample of ABI L1b data for each of the 16 bands.
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.

Lineage Statement These data were produced by the NOAA Office of Satellite and Product Operations (OSPO) and are archived at the NOAA National Centers for Environmental Information (NCEI).
Processor
  • DOC/NOAA/NESDIS/OSPO > Office of Satellite and Product Operations, NESDIS, NOAA, U.S. Department of Commerce
Processing Steps
  • Raw data downlink is received by the antenna system which processes the data through signal processing equipment to intermediate frequency. Forward error correction is performed. If FEC fails, those packets are dropped. Good packets are input to L0 processing. In L0 processing packets are uncompressed, extracted and byte-aligned (L1a). L1b processing extracts the L1a data, performs radiometric and geometric correction on the data to create L1b data.
