Spatial pollution rose pattern of SO2 in the vicinity of a typical thermal power station in India.

Air pollution is one of the greatest environmental evils. The Multi-Plume industrial source complex Short-term Period Regulatory (MPC-SPR) model is an alternate model to EPA and it is exclusively developed for regulatory purposes in India. The MPC-SPR model is based on a Gaussian Plume dispersion model from continuous elevated point sources. The processes as considered in the models are similar to ISCST3. The data requirements for dispersion analysis consist of three important parts: the emission inventory, the meteorological data and the monitoring data. A detailed emission inventory has been prepared by gathering data such as stack height, stack diameter, stack temperature, velocity, and rate of discharge of SO2 from the industries. Emission inventory has been Neyveli prepared data gathered from CARD such as stack coordinate, stack height, exit stack diameter and emission rate of SO2. The Meteorological data such as wind speed and Wind direction were observed from the Meteorological observatory at Vadalur. The hourly meteorological file to the MPC-SPR models have been prepared, which is similar to that of the ISCST3 model. The MPC-SPR Model was used to simulate the dispersion pattern of SO2 in the month of January 2019 by considering the emission from all the industrial stacks situated within the study area.
