Section “Atmospheric Physics”
The traditional research fields of Section “Atmospheric Physics” are following:
- Atmospheric dynamics;
- Physics of atmospheric boundary layer;
- Air pollution;
- Atmospheric microphysics and aerosol.
In recent years, research and development activities are increasingly orientated to environmental issues – different aspects of air pollution, chemical weather forecasting, local climate and its change due to anthropogenic influence. Study of the UV radiation, measurements of stratospheric ozone and prediction of ground-level ozone in the country is initiated during the last decade. New directions are studying the potential of alternative energy sources in the country, and atmospheric dynamics and pollution in urban areas and their relation to climate change.
UV radiation index values are published hourly on the website of the Institute as well as forecast for the next day (http://www.geophys.bas.bg/uv_index/uv_index_bg.php). Users can use online – calculator to estimate the acceptable time for sun exposure (http://www.geophys.bas.bg/total_ozone/total_ozone_bg.htm).
Values of total ozone concentration based on measurements at the Institute augmented with satellite data are published daily. Forecast of monthly average values is also available on-line (http://www.geophys.bas.bg/total_ozone/total_ozone_bg.htm).
Our investigations and efforts are part of the world scientific research with long standing traditions, and priority development. Proof of this is staff involvement in projects of the European Union and NATO, in the COST activities, and bilateral cooperation. The team participates in the development of several solutions implementation projects funded by the Executive Environment Agency, Ministry of Environment and Water and National Electric Company. The most considerable projects are a system for tropospheric ozone prediction in ambient air (http://data.geophys.bas.bg/ozone_surf/index.html) and a methodology for designing new industrial stacks and calculation of pollution concentration and distribution in the surface layer, approved as a national regulatory standard for evaluation of the anthropogenic impacts on the air quality (Order №РД-02-14-211 from February 25, 1998). Some of the researchers are involved in multiple expertises to assess the adverse impacts of different objects on the environment.
