DHMZ was founded 1947 and since then it is located on Grič 3 in Upper Town, old part of Zagreb. Before Croatia gained independence in 1991, it meteorological and hydrological service has been a part of the meteorological and hydrological service in the former Yugoslavia. After independence of Croatia, DHMZ operates as state service. Since 1992, Croatia has been member of the World Meteorological Organization, United Nations authoritative voice on Weather, Climate and Water.
It is important to say that, although DHMZ was founded in 1947, the oldest Croatian meteorological station operating continuously was Zagreb-Grič, established in 1861 and DHMZ has such invaluable data in its responsibility.
The DHMZ supports the economic and sustainable development of Croatia and assists in the protection of lives, goods and the environment by providing information on the following: weather, climate, hydrological and ecological events and climate extremes with the aim of mitigating their consequences in line with WMO recommendations and EU directives.
The DHMZ manages the meteorological and hydrological infrastructure, air quality monitoring infrastructure, as well as the national archives of meteorological, hydrological and other relevant data.
The DHMZ is a reliable and reputable international partner, particularly in southeastern and central Europe.
- Construction of infrastructure and measurement systems, as well as planning and maintenance of all kinds of meteorological and hydrological stations and air quality measurement stations
- Development and maintenance of various databases (meteorological, hydrological, air quality)
- Provision of information on meteorology, hydrology and air quality to users (the DHMZ issues warnings and produces analyses, forecasts, studies and surveys). This is achieved through the application of scientific methods and the use of powerful computers and sophisticated software in producing numerical models
- Applied scientific research and development of methods designed to enhance the quality of information which the DHMZ offers to its users.
- Operational implementation of hailstorm defense
- DHMZ products/services are used in the following areas: public information services, physical planning, Construction, strategic planning, urban planning, architecture, water resource management, electricity resource management, traffic, healthcare, sports, physical recreation, environment and nature protection, agriculture, civil protection, protection of lives
