Paper Abstract

Retrieval of reflectance spectra as well as of other level 2 products from hyperspectral remotely sensed data demands an accurate analysis of the attenuation and scattering effects due to aerosols and gases distributed in the atmospheric path. Starting from radiometrically corrected data, target reflectance spectra were obtained by solving the radiative transfer equation using a rather simple physical model, which also takes into account the effects of molecular (Rayleigh) and aerosol (Mie) scattering. We have also investigated the problem of how the environment surrounding the observed target may affect the radiance reaching the imaging sensor. By comparing simulated with measured data improvements in visible and near infrared spectral range with respect to the usually adopted inversion techniques are shown. Some examples of atmospheric correction on data acquired by the MIVIS imaging spectrometer, are presented and discussed.
