Percentage difference in the (a) BLH, (c) wind speed at 500 hPa, and (d) RH at 500 hPa observed between the PLD and DLD periods based on WRF-Chem simulations for India and the adjacent regions. (b) Concentration weighted trajectory (CWT) map of the AOD for Central India during the DLD period (March 25–April 20, 2020). The blue dot denotes the center of central India.
