| Zusammenfassung |
| A regional air quality simulation framework including the Weather Research
and Forecasting modeling system (WRF), the Community Multi-scale Air
Quality modeling system (CMAQ), and precursor emissions to simulate
tropospheric ozone over South and East Asia is introduced. Concentrations of
tropospheric ozone and related species simulated by the framework are
validated by comparing with observation data of surface monitoring, ozonesondes, and satellites obtained in 2010. The simulation demonstrates
acceptable performance on tropospheric ozone over South and East Asia at
regional scale. Future energy consumption, carbon dioxide (CO2),
nitrogen oxides (NOx), and volatile organic compound (VOC) emissions in 2030
under three future scenarios are estimated. One of the scenarios assumes a
business-as-usual (BAU) pathway, and other two scenarios consider
implementation of additional energy and environmental strategies to reduce
energy consumption, CO2, NOx, and VOC emissions in China and India.
Future surface ozone under these three scenarios is predicted by the
simulation. The simulation indicates future surface ozone significantly
increases around India for a whole year and around northeastern China in
summer. NOx is a main driver on significant seasonal increase of surface
ozone, whereas VOC as well as increasing background ozone and methane is
also an important factor on annual average of surface ozone in East Asia.
Warmer weather around India is also preferable for significant increase of
surface ozone. Additional energy and environmental strategies assumed in
future scenarios are expected to be effective to reduce future surface ozone
over South and East Asia. |
