Annotation	A comparison of retrieved tropospheric NO2 columns from satellite instruments SCIAMACHY and OMI with their model counterparts has been performed for one month’s simulation of the pair WRF-CAMx. A good correspondence has been found. A simplified version of optimum interpolation in the state space consisting of tropospheric columns has been run. The ratio of analysed to model column has been used as a scaling factor for model ground level NO2 concentrations. If the corrected concentrations fit better with observations, it may be an evidence of model bias in all vertical levels. If the correction is small but the model fit is poor, it may be an evidence of lack of representativity of the station.
