VAPS Icon "mfrsrcldod1min" Value-Added Product (VAP)

Active Dates: 12/21/2004 to 6/9/2008.

Description: Derived: Cloud Optical Properties from MFRSR, MWR, Langley Analysis

The mfrsrcldod1min value-added product produces cloud optical properties (optical depth and effective radius) from multi-filter rotating shadowband radiometer (MFRSR) , micorwave radiomter (MWR) and the Langley analysis Value Added Product (Langley VAP).

The mfrsrcldod1min value-added product (VAP) obtains cloud.optical depth and effective radius using a retrieval algorithm developed by Min and Harrison (1996) . The1-sigma uncertainties in these quantities are also estimated by propagating irrdiance, I0 , liquid water path and surface albedo. This version only considers the diffuse-horizontal irradiance at 415 nm (to avoid the gaseous absorption); the direct-normal irradiance is not included. Thus clouds with small optical depth ( < 7) would be considered as the outside of the operating regime of this VAP.
