Preliminary results of LOTOS model application for Russia

摘要

The first results of the comparison of the transport-photochemical model LOTOS with measurements of the surface ozone and some of its precursor concentrations over European Russia are presented in the paper. The model is developed at the Netherlands Organization of Applied Research (TNO). Test runs were performed for the year 1997. Comparison of output parameters like surface ozone and nitrogen oxides concentrations was done using the measurement datasets of TROICA-3 expedition, EMEP measuring network and Kislovodsk High Mountain Station (KHMS). The surface ozone concentration measured at KHMS is in a good agreement with the modeled values if the second but not the surface level of the model is chosen. Comparison of hourly mean modeled concentrations with latitude profile of TROICA-3 expedition shows a substantial concentration underestimation while approaching the Ural Mountains and in the regions of strong emissions. The best agreement is observed while comparing model concentrations with EMEP measurements. The comparison showed that the model reproduces reasonably well the spatial distribution and temporal variability of the surface ozone concentration and that it can be used for the tasks of regional ozone monitoring.
