Paper Abstract

A method for the determination of aerosol optical properties from imaging spectrometer data on a local scale is investigated, making use of the continuous spectral coverage, high spatial resolution, and the well-calibrated radiometry of such data. The method (correlated spectral unmixing) is based on the decomposition of the sensor signal in the short-wave infrared using spectrum database ground spectra, the reconstruction of image ground spectra in the visible, and forward modelling with a radiative transfer code. The sensitivity of the imaging spectrometer signal to different atmospheric condititions is explored, as well as the correlation of spectral reflectances in the visible and short-wave infrared for a variety of surfaces. The potential of the presented method is demonstrated for a scene from the airborne visible and infrared imaging spectrometer AVIRIS over rugged heterogeneous coastal terrain in California, and comparisons to multispectral methods are made.
