GRAP measures instrumental in the cleanup, say experts
The latest report by SAFAR (System of Air Quality and Weather Forecasting And Research shows that there is rapid decline in the levels of PM2.5 from 640μg/m3 on November 8, 2017 to 248μg/m3 on November 11, 2017 in Delhi. The conditions are likely to improve further.
Experts attribute the improvement to measures implemented under GRAP (graded response action plan) over the last few days.
Due to this decrease, further emergency measures are not likely to be needed. These levels will fall further up to 200-210μg/m3 till November 13, 2017 and remain in same range until Nov 15, 2017. These levels are close to background concentration range for November in Delhi.
The report also predicts that in the coming week, western disturbance would withdraw on November 16 with certain dip in temperature and possibility of increased moisture. This might increase pollution levels. SAFAR would measure the change in PM2.5 levels on November 14.
This increase is not likely to be as high as seen during the last few days.
