title: Trace atmospheric gases in the Karadag nature reserve in Crimea
abstract: Annual observations of surface concentrations of ozone and other atmospheric trace gases in the Karadag nature reserve, Crimea, are presented. Concentrations of primary air pollutants (oxides of carbon, nitrogen, and sulfur) were several orders of magnitude less than Russian maximum permissible levels throughout the year. Variations in the ozone concentration are close to those on rural terrains of the southern countries of western Europe. The diurnal maximum of ozone concentration is observed 2
