Remote Sensing Applications C-6.6 REMOTE SENSING OF PM10 FROM LANDSAT TM IMAGERY

Air pollution concentration has been estimated over Penang Island from Landsat TM 7. In-situ measurements of the corresponding air pollution parameter (particulate matter less than 10 micron, PM10) were carried out simultaneously with the acquisition of the satellite imagery. Three algorithms were introduced in the present study for the retrieval of PM10 for air pollution mapping and their accuracies were noted. The objective of this study was to test the feasibility of the proposed technique for retrieving air quality values by using the high spatial resolution Landsat TM7 imagery. Semi-empirical relationship has been used for PM10 mapping all over Penang Island. We used thermal infrared and visible wavelengths bands in this study. This study indicated that the satellite scene produced useful information for air pollution mapping. Daily remote sensing of aerosol from satellite over the land and ocean is essential to obtain the global aerosol budget to estimate the contribution of anthropogenic emission to the aerosol budget and to the aerosol radiative forcing of climate. Because of the short lifetime of aerosol particles an
