ERBE Like: Simplest processing mode. Unsophisticated cloud detection
and angular directional models. Consistent with earlier ERBE processing to
maintain consistency.
CERES Clouds and TOA/SFC Fluxes: Focus on Top-of-Atmophere
(TOA) radiation, includes parameterized models for surface radiation
estimation. Cloud detection using multi-spectral VIRS/MODIS imager. Vastly
improved angular distribution models allowing cloud property dependent
anisotropy. Time-space averaging includes 1hourly geostationary radiance data
to improve diurnal cycle modeling between CERES Flux measurements.
CERES Clouds and Computed Flux Profiles: Radiative transfer code
used to calculate in-atmosphere as well as surface fluxes. Treatment of
clouds using VIRS/MODIS retrieved cloud properties, multi-constituent
aerosols with satellite retrieved optical depths, scene and spectrally
dependent surface boundary conditions. Time-space averaging using
geostationary based cloud properties and grid scale radiative transfer.
