Abstract
Surface ozone sources and factors forming anomalous ozone concentration are discussed. The relations between elevated surface ozone concentrations, air temperature, and wind speed in planetary boundary layer are studied using data from Moscow, its environments and more far territories, Black Sea coast, foreign air quality stations. Impacts of advection of ozone and its precursors on ozone levels are shown. Studies of factors causing ozone episodes and reasons of below-average ozone concentrations under meteorological conditions, favorable for photochemical ozone production, are the base for interpretation and correction of ozone forecasting from chemistry-transport models.
