This computation involved: SRB satellite Staylor algorithm using ISCCP-C1 and ERBE data deployed on NASA Langley Atmospheric Science Data Center (ASDC). The primary data source is the International Satellite Cloud Climatology Project (ISCCP) C1 data product. Using the ISCCP C1 parameters as input, SRB results are generated using two different algorithms. The Pinker algorithm (developed jointly by Drs. R.T. Pinker and I. Laszlo form the University of Maryland) is a physical model which uses an iterative procedure based on delta-Eddington radiative transfer calculations. The Staylor algorithm (developed by Mr. W.F. Staylor from the NASA Langley Research Center) is a parameterized physical model in which both cloud and aerosol transmission characteristics have been separately tuned to historical data at various locations around the globe. Earth Radiation Budget Experiment (ERBE) data are also used as input to the models.
