ERBE Like: Simplest processing mode. Unsophisticated cloud detection
and angular directional models. Consistent with earlier ERBE processing to
maintain consistency.
CERES Simple: Focus on Top-of-Atmophere (TOA) radiation, includes
parameterized models for surface radiation estmation. Cloud detection using
multi-spectral VIRS/MODIS imager. Vastly improved angular directional models
allowing cloud property dependent anisotropy. Time-space averaging includes
1hourly geostationary radiance data to improve diurnal cycle modeling between
CERES Flux measurements.
CERES Complex: Radiative transfer code used to model 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.
