Comparison of GEO BB fluxes with SARB
Purpose
To check the consistency between the fluxes and the given cloud property and atmospheric inputs
SARB un-tuned flux estimates are from FU-Liou radiative transfer calculations based on input cloud property and GEOS profiles
Method
Compute SYN for July 2002 for one latitude band
Compare with CERES fluxes and MODIS cloud properties as a baseline
Compare with GEO derived broadband fluxes and GEO cloud properties
Errors due to both NB to BB and cloud property errors
Preliminary - first attempt results

Preliminary results show promise
Need to further study the large SW flux scenes and LW GEO cloud emissivities
Evaluate GEO fluxes with MODIS clouds
Evaluate CERES fluxes with GEO clouds
TISA will work with SARB to deliver SYN and AVG products in the near future
