Atmospheric correction of spectral imagery: evaluation of the FLAASH algorithm with AVIRIS data
Michael W. Matthew,Steven M. Adler-Golden,Alexander Berk,Gerald W. Felde,Gail P. Anderson,D. Gorodetzky,Scott E. Paswaters,Margaret Shippert +7 more
TL;DR: Comparisons of ground truth spectra with FLAASH-processed AVIRIS (airborne visible/infrared imaging spectrometer) data are shown, including results obtained using different processing options, and with results from the ACORN algorithm that derive from an older MODTRAN4 spectral database.

Analysis of Hyperion data with the FLAASH atmospheric correction algorithm
Gerald W. Felde,Gail P. Anderson,Thomas W. Cooley,Michael W. Matthew,Steven M. Adler-Golden,Alexander Berk,Jamine Lee +6 more
TL;DR: A new spectra; recalibration algorithm, which has been incorporated intoFLAASH, is described and results from processing Hyperion data with FLAASH are discussed.
Proceedings ArticleDOI
Validation of the QUick atmospheric correction (QUAC) algorithm for VNIR-SWIR multi- and hyperspectral imagery
Lawrence S. Bernstein,Steven M. Adler-Golden,Robert Sundberg,Robert Y. Levine,Timothy Perkins,Alexander Berk,Anthony J. Ratkowski,Gerald W. Felde,Michael L. Hoke +8 more
TL;DR: In this article, the spectral standard deviation of a collection of diverse material spectra, such as the end-member spectra in a scene, is essentially spectrally flat, allowing the retrieval of reasonably accurate reflectance spectra even when the sensor does not have a proper radiometric or wavelength calibration.
