Question:
I am surprised to see increased biogenic emissions in most of your
study region, although future increased temperatures and reduced precipitation
should reduce biogenic emission in many areas. This is caused by a fairly simple
pure-temperature based biogenic response to the model. (Christian Reuten)
Answer:
The biogenic emissions in our modeling system are temperature and
radiation dependent. As temperature and radiation increase in the future climate
biogenic emissions increase. Biogenic emissions in more sophisticated emission
models are dependent on several other parameters, which were, however, not
included in the current study.
Question:
Did you include changes in vegetation cover in future? (S. Adreani-
Askoyoglou)
Answer:
No, vegetation cover change was not included in the current modelling
study. We solely investigated the impact of changes in meteorological parameters
due to climate change on surface ozone.
Question:
Do you have an idea if this pattern of change in solar radiation in
ECHAM5 is also seen in other IPCC Models? (W. Lefebvre)
Answer:
The global circulation model ECHAM5 was used in the current study
only to force the regional climate model RegCM3, which we are actually using.
