Thirteenth Atmospheric Radiation Measurement (ARM) Science Team Meeting
The cloud optical depth retrieval proposed by Barker and Marshak (2001), which takes advantage of the abrupt change in shortwave surface albedo around a wavelength of 700 nm because of the presence of surface vegetation, is applied to three-dimensional cumulus cloud fields generated by large eddy simulation. Error analyses on the retrieved optical depths show the limits of the method for clouds with significant vertical structure. An analysis of the retrieval error for cloud fields measured during the Narrow Field-of-View Campaign at the Southern Great Plains Central Facility in the summer and fall of 2001 is also presented.
