The Czech Hydrometeorological Institute (CHMI), Czech: Český hydrometeorologický ústav (ČHMÚ), is within the Environmental Ministry of the Czech Republic (MoECR). The head office and centralized workplaces of the CHMI, including the data processing, telecommunication and technical services, are located at the Institute's own campus in Prague. The CHMI has four major divisions:^[1]

• Air Quality Control
• Meteorology
• Hydrology
• Finance and Administration

The National Meteorological Institute was established in 1919 shortly after the Czechoslovak Republic was established at the end of World War I. On January 1, 1993, Czechoslovakia peacefully split into two separate nations: the Czech Republic and the Slovak Republic. The National Meteorological Institute was re-named the Czech Hydrometeorological Institute and it's charter was amended in 1994 and in 1995 by the Ministry of the Environment of the Czech Republic.^[2][3]

The Air Quality Control division has five sections:^[4]

• Air Quality Information System
• Emission and Sources
• Modelling and Expertise
• Airborne Monitoring
• Ambient Air Quality Standards

The work of the Modelling and Expertise section is focused upon: the development of air pollution dispersion models; the application of such models in the preparation of expert reports and opinions; forecasts of air quality control; the processing of operating information on pollutant concentrations obtained by the Airborne Monitoring section.

The SYMOS97 air pollution dispersion model was developed at the CHMI. It models the dispersion of continuous, neutral or buoyant plumes from single or multiple point, area or line sources. It can handle complex terrain and it can also be used to simulate the dispersion of cooling tower plumes.^[5]
