CERES Scene IDs



Scene Identification Description

  • The CERES ADMs, Angular Directional Models, are used to convert CERES radiances into fluxes based on IGBP link to external site surface type classification, MODIS cloud properties and GFDL-GEOS atmosphere to ensure no flux biases according to scene.
  • The CERES ADMs show no dependencies with cloud properties, viewing geometry or surface type.
  • The CERES ADMs and scene identification is a great improvement over the historical ERBE ADMs, which employed only 12 scene types, especially clear-sky identification, polar clouds, and coastal regions.
  • More information can be found in the SSF Data Quality Summary (DQS) link to external site and (Loeb et al 2005), and (Loeb et al 2007)
