DETECTION OF SAHARAN DUST BY SPATIAL/SPECTRAL SIGNATURES IN VIS-TIR SATELLITE RADIANCES

摘要

This paper will face the problem of detecting dust clouds, discriminating them from meteorological clouds, by using multispectral radiances measured from satellite sensors. The possibility to overcome problems related to their very similar spectral signatures by combining an advanced multi-temporal satellite data analysis approach with a peculiar spatial/signature, will be described using as study case a dust-storm event occurred in North Africa in 1997.
