About us

The Slovak Hydrometeorological Institute (SHMI) is a specialized organization providing hydrological and meteorological services at the national and international level. The SHMI was established by the former Ministry of Forestry and Water Management on 1 January 1969, and the scope of its activities is currently laid down in Act no. 201/2009 on state hydrological and meteorological services. The SHMI is the successor of institutions that were providing hydrological and meteorological services in Slovakia from the mid-19th century. It is state-subsidised organisation operating under the Slovak Ministry of Environment.

The SHMI's activities include the following: monitoring of quantitative and qualitative parameters of the air and water in Slovak territory; collecting, verifying, interpreting and archiving data and information on the condition and regime of air and water; describing developments in the atmosphere and hydrosphere; and issuing forecasts, warnings and other information regarding the atmosphere and hydrosphere. All the aforementioned data, information and other research are made available to the public.

The SHMI obtains most of its data on the quantity and quality of air and water from the various monitoring facilities of the state hydrological and meteorological network. There were 3,884 such facilities in 2011 and they comprised the following:

SHMI state monitoring network

Network specification Number of facilities

State meteorological network

meteorological stations 34
climatological stations (voluntary) 73
rain-gauge stations 550
automatic rain-gauge stations 76
solar radiation measuring stations 5

air quality monitoring stations 38
monitoring stations for regional air pollution and  rainwater quality 4
monitoring stations for environmental radioactivity 26
total atmospheric ozone measuring station 1

State hydrological network

surface water measuring stations 420
spring monitoring facilities 361
groundwater observation boreholes 1135
monitoring sites and facilities for collecting data on surface water quality (including the automatic warning station) 448
monitoring facilities for groundwater quality 435

One of the SHMI's most relevant task is to provide information about air and water as well as about the weather and hydrological situation. A key aspect of the institute's activities in this regard is international cooperation and the exchange of data with counterpart services abroad.

The main task is to operate an integrated nation-wide monitoring system for all key aspects of the atmosphere and hydrosphere: i.e. water quality and quantity, air quality, weather, climate, and environmental radioactivity. In this regard, the SHMI's principal activities include:

  • managing the state hydrological and meteorological networks;
  • providing information on atmosphere, air quality, climate, water sources, and environmental radioactivity, at the national and international level;
  • producing and distributing weather forecasts and hydrological forecasts, and issuing warnings on dangerous hydrometeorological phenomena (such as high smog or ozone levels,  radioactive contamination), for the government, state administration bodies, municipalities, crises management authorities, the general public, and other domestic and foreign customers;
  • monitoring climate system development;
  • participating in the planning, arrangement and analysis of environmental projects;
  • participating in the development of strategic and conceptual documents for the environmental management in Slovakia;
  • participating in the reporting process to the EC, OECD, WMO and other national and international organizations;
  • collecting, processing and evaluating national air emissions;
  • coordinating the national programme of air and water monitoring;
  • reporting meteorological and hydrological data and radioactivity data to the WMO on-line telecommunication system;
  • providing meteorological data for civil aviation;
  • providing data, information and know-how for the Hydrometeorological Service of the Slovak Armed Forces.
