SSF1deg-lite Documentation


SSF1deg-lite Product Features

  • A 10yr dataset with an abbreviated parameter list of monthly and daily data with the latest CERES instrument calibration
  • This product provides the CERES observed Top-of-Atmosphere fluxes, associated MODIS clouds and aerosol properties and GEOS-4 atmosphere
    • Fluxes and clouds have been diurnally averaged using ERBE temporal interpolation (constant meteorology between CERES measurements).
    • The Edition2.6 product contains the observed fluxes with the latest CERES instrument calibration.
  • Provides a long term climate record dataset, relying on the fewest input datasets
  • Provides parameterized surface fluxes (not observed)
    • Radiative transfer computed surface fluxes provided in the SYN1deg product.
  • Also designed to be compared with other Terra or Aqua based satellite products.
    • Diurnal averaging based on constant meteorology at the time of the Terra (10:30LT) or Aqua (13:30LT) overpass times and does not account for regional diurnal changes in flux and cloud properties.
    • The diurnal cycle is taken into account in the SYN1deg product.
  • The SSF1deg input instantaneous footprint level fluxes and cloud properties can be found in the SSF Level2 product.
  • Applicable Studies:
    • Angular dependent of radiance
    • Cloud and aerosol properties comparison
    • Cloud and aerosol radiative forcing estimate and comparison with other estimate
    • Comparison of radiation, aerosol and cloud properties with model other then GCM (ie. LES, CRM)
    • Comparison with GCMs
    • Instrument study
    • Interpretation of radiation cloud and aerosol property variability
    • Surface flux calculation with simple transfer model
    • TOA flux only comparison
