TheCzech Hydrometeorological Institute (CHMI;Czech:Český hydrometeorologický ústav (ČHMÚ)) is the central state office of theCzech Republic in the fields ofair quality,meteorology,climatology andhydrology. It is an organization established by theMinistry of the Environment of the Czech Republic. 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 inPrague.
The National Meteorological Institute was established in 1919 shortly afterCzechoslovakia was established at the end ofWorld War I. On 1 January 1954, the National Meteorological Institute was united with the hydrology service and the Czech Hydrometeorological Institute was established. Its charter was amended in 1994 and in 1995 by the Ministry of the Environment of the Czech Republic.
The CHMI is made up of three specialized sections (meteorology andclimatology section,hydrology section, andair quality section) with two support sections (finance and administration andInformation technology (IT) section), and finally, the director section.[1]
In addition to the central office in Prague-Komořany, the CHMI has a regional offices (branches) in six other Czech cities, not all sections are represented in each branch. Those other offices are inBrno,Ostrava,Plzeň,Ústí nad Labem,Hradec Králové, andČeské Budějovice.
The Air Quality division has seven departments:[2]
The work of the Modelling and Expertise Pool department is focused upon: the development ofair 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 ofcontinuous, neutral or buoyant plumes from single or multiplepoint, area or line sources. It can handle complex terrain and it can also be used to simulate the dispersion ofcooling tower plumes.[3]
