Satellite-Based PM Annual Compliance Monitoring for Northern Italy: A PASODOBLE Downstream Sub-Service
Abstract
Aerosol satellite remote sensing can be profitably exploited in Air Quality monitoring in order to estimate the particulate matter (PM) concentration at surface level. In this work MODIS level 2 aerosol data are employed in a semi-empirical approach to produce daily maps of concentration of PM2.5 and PM10 at the spatial resolution of 10×10 km2 over the Northern Italy domain for the 2004 - 2009 period. Then monthly and annual averaged maps are calculated for the whole domain in order to investigate the spatial patterns of PM concentration in this highly polluted area. Furthermore, for exploring the possibility of a satellite-based monitoring of PM concentrations threshold exceeding also in areas where ground-based measurement sites are not present, relative percentile maps of exceedances over critical thresholds are calculated and critically analyzed.
