Abstract

The High-accuracy Atmosphere Correction for Hyperspectral Data (HATCH) algorithm retrieves surface reflectance from imaging spectrometer data in the 350-2500nm wavelength region with resolutions of 5nm or greater. A key feature of HATCH is that it derives calibration for the sensor spectral response functions (band centers and FWHMs) from the data themselves. This is approached by utilizing known atmospheric absorption features (e.g. water vapor and oxygen bands) and the application of a new technique dubbed the
