TLDR
Conditional Bivariate Probability Function plots revealed that the maximum concentrations of PM2.5 and PM10 were carried by north westerly winds (north-western Indo Gangetic Plains of India) and the seasonal differences in VE contributions were not very striking.About:

Exceedances and trends of particulate matter (PM2.5) in five Indian megacities.
TL;DR: The variability, trend, and exceedance analysis of PM2.5 measured at US Embassy and Consulate in five Indian megacities for six years suggests a statistically significant decreasing trend and can be attributed to the recent policies and regulations implemented in Delhi and other cities for the abatement of air pollution.

Temporal variation characteristics and source apportionment of metal elements in PM2.5 in urban Beijing during 2018-2019.
Shuang Zhao,Hezhong Tian,Lining Luo,Huanjia Liu,Bobo Wu,Shuhan Liu,Xiaoxuan Bai,Wei Liu,Xiangyang Liu,Yiming Wu,Shumin Lin,Zhihui Guo,Yunqian Lv,Yifeng Xue +13 more
TL;DR: Results of 72-h backward trajectory analysis of air masses showed that, except for local emissions, atmospheric metal pollution in Beijing is also affected by regional transport from Inner Mongolia, Hebei, the Bohai Sea and Heilongjiang.
