Abstract: The spectral characteristics are a key to remote sensing applications. The extraction of meaningful information from the imagery necessitates good knowledge and understanding of the spectral characteristics of the satellite sensors. Multispectral satellite sensors record information in wide of spectral channels. The spectral response in specific wavelength plays a major role in remote sensing applications. PM10 estimation using remote sensing is now becoming popular approach for pollution monitoring. Several approaches have been used for estimation of PM10 using various satellite sensors. This paper presents the sensitivity of satellite sensors at different wavelengths and its application to estimate PM10. The atmospheric absorption, reflectance and transmission behavior for Visible and Infrared ranges is a key to particulate matter monitoring. The sensitivity of different channels of MODIS, MERIS, SPOT5, Landsat TM/ETM+ and Landsat 8 have been analyzed. The sensor characteristics have also been presented to find the suitability of these sensors for PM10 distribution.
