Validation of Atmospheric Correction of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) Radiance Data Based on Radiative Transfer Modeling

摘要

An evaluation of atmospheric correction of AVIRIS data using radiative transfer codes LOWTRAN7 and MODTRAN is presented. The algorithm employed is based on a simple model of radiance L at each wavelength at the sensor that can be written approximately LAV=LpTp, where subscript AV referes to AVIRIS, Lp is the path radiance and Tp is the diffuse direct transmitted radiance of the atmosphere at AVIRIS.
