OZONE

• profils are grouped in general with one or two models out of the group• missed “flights” for every models• STD platform dependant:

• overestimated for ferry (30 meters)• more or less for arat (< 1000 but sharp RS)• underestimated for aztec and merlin (more level flight)

NO2

• simulated peaks are too strong• UAM-total really different behaviour• STD very different according to the platform :

• really overestimated for arat (mainly <1000m but sharp RS) in a lesser extend in Rams and Mocage and in a greater extend for Chimere and UAM

NO

• mis-representation both for back-ground values and peaks• simulated series are too smooth • overestimation in Chimere (Lisa and Acri) and Azur for ferry concentrations• underestimation of the STD

NO

NO

• synthesis representation for corr,rmse and std will be really useful• analyse by flight groups : AM/MD/PM/Land/Sea• when more models, track the ressemblance (like Chimere-LISA and Azur) ; not like in MTO, Mocage doesn’t appear isolated (even for NO)• As they are identical flight pattern, exploration also of the ability of models to reproduce the inter-day variability (mean, std, max, etc)
