Abstract

A combination of good spatial and spectral resolution makes visible to shortwave infrared spectral imaging from aircraft a highly valuable technology for remote sensing of the earth's surface. Many applications require the elimination of atmospheric effects caused by molecular and particulate scattering; a process known as atmospheric correction, compensation, or removal. The Fast Line-of-sight Atmospheric Analysis of Spectral Hypercubes (FLAASH) atmospheric correction code derives its physics-based algorithm from the MODTRAN4 radiative transfer code. A new spectral recalibration algorithm, which has been incorporated into FLAASH, is described. AISA (Airborne Imaging Spectrometer for Application) data covering the Eastern Sea in China was acquired and the results from processing AISA data with FLAASH are discussed.
