Abstract: Recent regulatory policies in East Asia reduce ozone precursors, but these changes are spatially and temporally nonuniform. This study investigates variations in the long-term trends of tropospheric NO2, HCHO, and HCHO/NO2 ratios to diagnose ozone… read more here.

DOI: 10.1016/j.jenvman.2017.02.024
Abstract: In rural area, due to the reduction of NOx and CO emitted from vehicle exhausts, the ozone photochemical reaction exhibits relatively weak effect and ozone formation presents different pattern with its precursors in contrast to… read more here.

DOI: 10.1088/1748-9326/ae17da
Abstract: Current air quality monitoring through the EPA’s Air Quality System (AQS) network faces significant coverage gaps particularly in vulnerable communities that experience disproportionate exposure to air pollutants. While satellite instruments provide extensive geographic coverage for… read more here.
