Air Quality Interpretation of Four Geographically Distinct Hot Spot States of India-An Appraisal Using Aerosol Optical Depth and Particulate Matter

The application of Moderate Resolution Imaging Spectroradiometer-Aerosol Optical Depth (MODIS-AOD) for Air Quality (AQ) assessment has contributed significantly by making use a spatiotemporal relationship between ground-level particulate matter and aerosol optical density at both city state levels. Traditional ground-based site-specific monitoring method found profound gap in their spatial coverage. Such challenging situations prevail over the progressive development combined usage ground technique along with MODIS-AOD product (with 10 km resolution). This was achieved derived assembling satellite sensor, Terra as tool regional-based specific studies airborne particles. Their analytical linear association evaluated explored feasibility either Respirable Suspended organic Matter (RSPM) or AQI spatiotemporally distinct geographical sites situated four States India. Examined interrelationship RSPM-AOD against meteorological drivers through Principal Component Analysis (PCA) Quantitative Risk Assessment (QRA) focussed zones. Elevated Pollution noticed urban industrial cities Pune, Kochi, Chennai. They were flanked various clusters substantial personal handling vehicles. A region-wise correlation recorded categorized areas: WS1, WS2, SW, ES. Each zone subsequently judged noteworthy linked ground-monitored RSPM data retrieved AOD output. means records could represent component; consequently, infer sources origin later days come up reasonable emission control channels. India Maharashtra, Karnataka, Kerala, Tamil Nadu, are ES respectively.
