ABSTRACT

The presented work is aiming at climate change impacts and vulnerability assessment in
Bulgaria. Climate change may affect exposures to air pollutants by affecting weather
and thereby local and regional pollution concentrations, by affecting anthropogenic
emissions (emission scenarios), by affecting natural sources of air pollutant emissions
(biogenic VOCs) and by affecting many other processes. Local weather patterns
(namely temperature, precipitation, clouds, atmospheric water vapor, wind speed, and
wind direction) influence atmospheric chemical reactions; they can also affect
atmospheric transport and deposition processes as well as the rate of pollutant export.

US EPA Models-3 System (MM5, CMAQ and partly SMOKE) for a region with
resolution of 10 km covering Bulgaria is exploited, here. The meteorological input is
produced by the climatic version of ALADIN weather forecast system and TNO
emission inventory for 2000 is used. The chemical boundary conditions are extracted
from results of 50-km runs over Europe made in Aristotle University of Thessaloniki,
Greece. Calculations for the period 1990-2000 are performed, results presented in the
study. For year 2000, some scenarios are run, results compared with measuring data.

Keywords: Climate change impact assessment, Air quality, Air pollution levels.
