<abstract>
<p>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 meteorological forcing on surface
ozone. The RegCM3 regional climate model was firstly constrained by the
ERA40 reanalysis dataset which is considered as an experiment with perfect
meteorological boundary conditions and then it was constrained by the global
circulation model ECHAM5. A number of meteorological parameters were
examined including the 500 mb geopotential height, solar radiation,
temperature, cloud liquid water path, planetary boundary layer height and
surface wind. The different RegCM meteorological forcing resulted in changes
of near surface ozone over Europe ranging between &amp;plusmn; 4 ppb for winter and
summer. The area showing the greatest sensitivity in O&lt;sub&gt;3&lt;/sub&gt; during winter
is central and southern Europe while in summer central north continental
Europe. The different meteorological forcing impacts on the atmospheric
circulation, which in turn affects cloudiness and solar radiation,
temperature, wind patterns and the meteorology depended biogenic emissions.
For comparison reasons, the impact of chemical boundary conditions on
surface ozone was additionally examined with a series of sensitivity
studies, indicating that surface ozone changes are comparable to those
caused by the different meteorological forcing. These findings suggest that,
when it comes to regional climate-air quality simulations, the selection of
external meteorological forcing can be as important as the selection of
adequate chemical lateral boundary conditions.</p>
