Sources and regional attributions to upper troposphere nitrogen oxides during the Asian Summer Monsoon 2022
Listed in National Center for Atmospheric Research
This study investigates the sources and regional attributions of nitrogen oxides (NO x ) in the upper troposphere|upper tropospheric (UT) during the Asian Summer Monsoon (ASM).
Description
The importance of South Asia (SA) and East Asia (EA) contributions is the subject of main interest. Using artificial tracers in a chemistry‐climate model, simulations with tracers from surface anthropogenic and lightning sources in SA and EA are conducted.
Model results are validated with airborne observations from the Asian Summer Monsoon Chemical and Climate Impact Project (ACCLIP) campaign in 2022 over the West Pacific. Good agreement between modeled and observed NO x is found in the UT. The results indicate that within the ASM anticyclone, both SA and EA sources significantly contribute to the UT NOx, with contributions of 41% and 36%, respectively.

While in the ACCLIP region during 2022, EA sources play a more important role, accounting for 50% compared to 19% from SA sources.
