Changes in Nitrogen Dioxide and Ozone over Southeast and East Asia between Year 2000 and 2030 with Fixed Meteorology

Abstract

ABSTRACT1) IIASA 'current legislation' (CLE), where current air quality legislation around the world is implemented; 2) IIASA 'maximum feasible reduction' (MFR), in which all currently available technologies are applied to achieve maximum emission reductions; and 3) the IPCC-SRES A2 scenario, which was used as a high emission estimate in the last IPCC assessment report. While increases in NO 2 and ozone are calculated when using the CLE scenario, reductions are seen for the MFR scenario. In the SRES A2 case, increases in NO 2 are largest, locally leading to ozone reductions at the surface resulting from titration effects. The model calculations suggest that air Terr. Atmos. Ocean.

“…The combustion of air leads to the formation of nitrogen oxides (NOx = [NO 2 + NO]) (Aragão et al 2014), which is toxic to biosphere species. It converts to nitric acid (HNO 3 ) and contributes to the acid rain, which is harmful to the entire ecosystem (terrestrial + aquatic) (Gauss et al 2007). The NO 2 is an important catalyst in the production of Tropospheric ozone (Zoran et al 2020).…”
