SFC Product Features

  • The Monthly Gridded TOA/Surface Fluxes and Clouds (SFC) archival product contains hourly single satellite flux and cloud parameters averaged over regions in a 1.0-degree nested grid.
  • The data are processed and written in local time.
  • Input to the SFC Subsystem is the Single Scanner Footprint TOA/Surface Fluxes (SSF) Level2 archival product.
  • Each SFC covers a single month swath from a single CERES instrument mounted on one satellite.
  • The product is written in HDF and contains metadata as well as gridded science data.
  • For TRMM, data will be organized onto 8 SFC HDF files, each containing data for ten 1.0-degree equal-angle zones.
  • For Terra and Aqua, data will be organized onto 36 SFC HDF files, each containing data for five 1.0-degree equal-angle zones.
  • Each record contains spatially averaged data for an individual region.
  • The science data are Vdata with multiple records.
  • The major categories of data output on the SFC are as follows:
    • Region data.
    • Imager Radiances Statistics.
    • Angular model scene classes.
    • Total-sky radiative fluxes at TOA and Surface.
    • Clear-sky radiative fluxes at TOA and Surface.
    • Surface Emissivity.
    • Cloud category properties for four cloud layers.
  • Applicable Studies:
    • Cloud and aerosol properties comparison.
    • Surface flux calculation with simple transfer model.
    • TOA flux only comparison.
