    • GOES-R SERIES Advanced Baseline Imager (ABI) Instrument Calibration Data

    Metadata Updated: January 1, 2024

    The ABI Instrument Engineering Telemetry Data file contains data used to support the generation of ABI Level 1b products, and monitor and evaluate the health and performance of the instrument. This data is transmitted to the ground in raw digital counts, and subsequently converted into physical units by the ground system. Most of the data pertains to the temperature of components in the instrument. This includes the ABI Infrared Calibration Target (ICT), the North-South and East-West scan mirrors, the three focal plane modules (i.e., VNIR, MWIR, LWIR), and the ABI optical bench. Temperatures are expressed in units of kelvin. The only exception to this is the data for the twelve platinum resistance thermometers (PRTs) associated with the ICT. These data PRT data are expressed in counts. Table C.1, ABI Instrument Engineering Telemetry in Appendix C identifies each telemetry parameter. Elements of the instrument telemetry support the generation of the ABI Level 1b Radiances product data. The North-South scan mirror, the East-West scan mirror, and the PRT counts contribute to the computation of gain coefficients for detectors in the ABI emissive channels during observations of the ICT and the Space Look. Additionally, the scan mirror temperatures are used in support of determining the Earth scene radiances for the emissive bands. The ABI Instrument Calibration Data files contain data resulting from the observation of the ABI Space Look, Infrared Calibration Target (ICT) (i.e., blackbody), Star Look Target, and Solar Calibration Target (SCT) (i.e., solar look target). These observations are dependent on the ABI band and the individual detectors. The ABI Lunar Scan Data file contains an off-earth mesoscale scene, and is collected as part of an ABI mode 3 or mode 6 timeline when the moon is in the field of regard of the ABI instrument. The apparent size of the moon in the field of regard of the ABI subtends a size suitable for coverage using the ABI mesoscale scene type, which consists of two swaths. This data is collected for all ABI bands. Lunar scan data samples are radiometrically calibrated. The moon is observed in support of off-line ABI calibration activities.
