However, for background purposes, past decade s meteorological data including available data on inversion heights, frequency and duration of incidence from the nearest IMD observatory will be collected. Based on meteorological data wind roses (both seasonal and annual) will be prepared. A critical comparison between long term meteorological data and three months meteorological data measured at site will be made to finalise the input of mathematical modelling. Additional information regarding the terrain will be used to determine the adequacy of the meteorological as well as to finalise the input for subsequent air quality modeling.
