Validation of models AEROFOUR and AEROPOL using the model validation kit established at Mol

The AEROPOL and AEROFOUR dispersion models developed at Tartu Observatory (Estonia) are validated using the Lillestrom dataset and following the model comparison rules established at the workshop in Mol. Running the AEROFOUR model, the vertical wind and temperature co-variations not included into the official dataset were used. The computed and measured arc-wise maximum and crosswind integrated concentrations match fairly. No clear tendency of over or under-prediction was found. The best performance was achieved by AEROFOUR model with the above-mentioned covariations included into the initial dataset. This demonstrates that the detailed measurement techniques give clear advances for model estimations if the model is designed to use this kind of data.
