A fast look-up-table (LUT) method to retrieve broadband surface transmission and top-of-atmosphere albedo is validated. The LUT methodology uses the LaRC modified Fu-Liou 2-stream delta-eddington, correlated-k, 18-band, shortwave radiative transfer model to produce a pseudo eleven dimension look-up-table. Narrowband retrievals of cloud properties of optical depth, phase, particle size and height are validated against in-situ surface observations from ARM, BSRN, SURFRAD and CERES TOA shortwave. Quality inputs of aerosol optical depth and single-scatter albedo ,surface albedo, surface type and elevation, precipitable water, column ozone and solar zenith angle are assumed.
