Case Study
A statistical approach is used to study the impact of wind speed and direction on ambient RSPM concentration at three different urban sampling locations in Nagpur. Directional parameters play an important role in determining the RSPM levels in ambient air. The use of circular statistics in modeling the RSPM concentration using wind direction is suggested. The nonlinear model based on inverse relationship of RSPM concentration with wind speed and sine and cosine of wind direction is used to obtain one-step ahead forecast. The results are compared with benchmark persistence model.
