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)
