Atmospheric correction of hyperspectral data using MODTRAN model

摘要

The solar radiance obtained by a sensor is modified by atmosphere interaction, affected by its path through theatmospheric absorption and scattered in the combined Sun-surface-aircraft. In this paper, we described a method usingRTM to simulate atmospheric spectral for deriving surface reflectance from Hyperspectral data (Hyperion). Preliminaryapplication of the technique to Hyperion data indicates that the retrieval results are reasonable, and available techniquesincluding retrieval of water vapor amount with MODTRAN look-up- table.
