Atmospheric correction validation and refinement using ground-based radiometry at Davis, CA
2005
First-principles atmospheric correction of earth-viewing spectral imagery requires atmospheric property information derived from the image itself or measured independently. A field experiment was conducted in May, 2003 at Davis, CA to investigate the validity and consistency of atmospheric properties and surface reflectances derived from simultaneous ground-, aircraft- and satellite-based spectral measurements. The experiment involved the simultaneous collection of HyMap and Landsat-7 imagery, in-situ reflectance spectra of calibration surfaces, and sun and sky radiances from ultraviolet and visible multi-filter rotating shadowband radiometers (MFRSRs). This paper briefly describes the experiment, data analysis and key results.
