This work is an extended evaluation of near-surface ozone as part of the global reanalysis of atmospheric composition, produced within the European-funded project MACC (Monitoring Atmospheric Composit...
Decadal regional air quality simulations over Europe in present climate: near surface ozone sensitivity to external meteorological forcing
Decadal regional air quality Europe surface ozone external meteorological forcing
2010/12/28
Regional climate-air quality decadal simulations over Europe were carried out with the RegCM3/CAMx modeling system for the time slice 1991–2000, in order to study the impact of different meteorologica...
The relative importance of various source regions on East Asian surface ozone

A tracer study has been performed for two summers in 2003 and 2004 with a regional chemistry-transport model in order to evaluate the potential constraint that tropospheric ozone observations from nad...
Increasing surface ozone concentrations in the background atmosphere of Southern China, 1994–2007
Increasing surface ozone concentrations background atmosphere Southern China
2009/9/2
Tropospheric ozone is of great importance with regard to air quality, atmospheric chemistry, and climate change. In this paper we report the first continuous record of surface ozone in the background ...
