Figure 2. The PM2.5 concentration in megacity Delhi and its neighbourhood are mainly dominated by local emissions and can be managed reasonably well through the GRAP implementation focusing on the NCR (top row). Strong meteorological influences at synoptic and interannual are also observed as summarised by the plots in bottom row, for mean PM2.5 (c), wind speed (d; WS), wind direction (e; WD) and atmospheric mixing by boundary layer height (f; BLH) during the October-November period at an interval of 15 days.
