Abstract: Some extensive numerical simulations of the atmospheric composition fields in Bulgaria have been recently performed. The numerical experiments performed produced a huge volume of information, which was used as a basis for evaluation and clarification of the atmospheric composition climate of Bulgaria. It is natural, in such a case, that the model results should be validated by comparison with measured data. The outcome of these comparisons is demonstrated and discussed in the present paper. The overall conclusion is that the agreement of simulated and measured concentration is reasonable enough, so the created computer simulation dataset is reliable and can really be used for atmospheric composition climate assessments.
