Conclusion
MOCAGE : able to provide reasonable large scale field
Studies performed so far show that chemical modeling in this area is highly sensitive to
Chemical scheme use (SAPRC-RACM)Inventories (mainly for primary coumpounds)Chemical boundary conditionsSpin-up
(see Observed and modelled chemical weather during ESCOMPTE, Atm. Res.)
Different problems Some morning vertical distribution High ozone concentration over sea
MERA station and MOZAIC profiles in process
