AB: A paper presents the results of LOTOS model validation and application for the estimates of daily, monthly and annually mean concentrations of surface ozone over Europe including European part of Russia. The study was carried out using mesoscale transport-photochemical model LOTOS on the basis of several scenarios runs with changing anthropogenic emissions and parameterization of ozone deposition on the surface. LOTOS model is developed in the Netherlands Organization of Applied Scientific Research. It takes into account modern approaches for 3D advection, horizontal and vertical diffusion, chemical transformations, dry and wet deposition and anthropogenic and natural emissions and has resolution of about 30×30 km. The model was validated on the basis of Russian ozone-measuring network data and data of TROICA expeditions and showed a reasonable agreement for 1997 model year. The estimates of emissions impact were carried out on the basis of real emission values for 1999. The scenarios of doubling of European (including Russia), only Russian and only European anthropogenic emissions were studied. It was shown, that doubling of anthropogenic emissions by all the Europe has the highest response in the emissions regions and distributed not uniformly over domain with substantial winter decrease (up to -60%) and summer concentration increase (up to 15%). Details of surface ozone response at individual sites are olso discussed. The work is carried out under the support of Russian Foundation for Basic Research ('03-05-64712).
