Inferring Optical Depth of Broken Clouds above Green Vegetation Using Surface Solar Radiometric Measurements
Journal of the Atmospheric Sciences
A method for inferring cloud optical depth is introduced and assessed using simulated surface radiometric measurements produced by a Monte Carlo algorithm acting on fields of broken, single-layer, boundary layer clouds derived from Landsat imagery. The method utilizes a 1D radiative transfer model and time series of zenith radiances and irradiances measured at two wavelengths, 1 and 2 , from a single site with surface albedos Ͻ . Assuming that clouds transport radiation in accordance with 1D theory and have spectrally invariant ␣ ␣ 1 2doi:10.1175/1520-0469(2001)058<2989:iodobc>2.0.co;2 fatcat:hz3yool7ird5zpnl35hb6rtp6m
