Extended Data Fig. 5: Observed decreases in surface PM2.5 during 2017–2022 for each season.

From: Recent PM2.5 air quality improvements in India benefited from meteorological variation

Extended Data Fig. 5

Seasonal mean PM2.5 measured at CAAQM and U.S. AirNow continuous monitoring sites during 2017–2022 for (a) March–May (MAM), (b) June–August (JJA), (c) September–November (SON), and (d) December–February (DJF). Note that DJF for 2017 represents December 2017 to February 2018. The larger dots with black circles represent PM2.5 concentrations at non-attainment cities that are available for six consecutive years. The smaller dots without black circles represent PM2.5levels for cities without six consecutive years of data.
