SSF Level2 Documentation

  • SSF Collection Guide — An overview of the science product along with definitions of each of the parameters included within the product.

SSF Level2 Product Features

  • This product provides the CERES observed Top-of-Atmosphere fluxes, associated MODIS clouds and aerosol properties and GEOS-4 atmosphere at the instantaneous footprint level
  • First available CERES product
  • Provides parameterized surface fluxes (not observed)
    • Radiative transfer computed surface fluxes provided in the CRS Level2 product
  • Also designed to be compared with other Terra or Aqua based satellite products
    • Footprint data (20km) can easily be collocated with other dataset
  • Additional Daily, and Monthly Product information can be found in the SSF1deg product.
  • Applicable Studies:
    • Angular dependent of radiance
    • Cloud and aerosol properties comparison
    • Cloud and aerosol radiative forcing estimate and comparison with other estimate
    • Interpretation of radiation cloud and aerosol property variability
    • Surface flux calculation with simple transfer model
    • TOA flux only comparison
    • Comparison of radiation, aerosol and cloud properties with model other then GCM (ie. LES, CRM)
