SMHI

SMHI is an abbreviation for "Sveriges Meteorologiska och Hydrologiska Institut", which is Swedish for "Swedish Meteorological and Hydrological Institute". SMHI is a government agency in Sweden and operates under the Ministry of Sustainable Development. [ [http://www.smhi.se/en/ SMHI web site] click on About 'SMHI', then on 'SMHI in brief'] SMHI has expertise within the areas of meteorology, hydrology and oceanography, and has extensive service and business operations within these areas.

SMHI's head office is located in Norrköping. Prior to 1975 it was located in Stockholm but after a decision taken in the Swedish Parliament (The Riksdag) in 1971 it was relocated to Norrköping in 1975. SMHI also has offices in Stockholm, Göteborg, Malmö and Sundsvall. To the Swedish public SMHI is mostly known for the weather forecasts in the public-service radio provided by Sveriges Radio. Many of the other major media companies in Sweden also buy weather forecasts from SMHI.

taff and organization

SMHI has about 600 employees. The research staff includes some 55 scientists, 45 at the Research Unit and 10 at the Rossby Centre. The research division is divided into six units: [ [http://www.smhi.se/en/ SMHI web site] click on 'Research'] [http://www.knmi.nl/samenw/cliwa-net/description/smhi/ Rossby Center and SMHI] ]

* Meteorological prediction and analysis
* Air quality
* Oceanography
* Hydrology
* Regional climate modelling (at the Rossby Centre)
* Remote sensing and radiation

The regional climate modelling is at the Rossby Centre, which was established at SMHI in 1997. Environmental research spans all six research units. There is also a project for providing contributions to the HIRLAM (High Resolution Limited Area Model) project.

The main goal of the research division is to support the Institute with research and development as well as to participate in many national and international research projects.

Air quality research

The air quality research unit of SMHI has 8 scientists, all of whom have expertise in air quality, atmospheric pollution transport, and atmospheric pollution dispersion modelling. [ [http://www.smhi.se/sgn0106/if/FoUl/en/staff/staff.html Air quality research staff] ]

Some of the atmospheric pollution dispersion models developed by the air quality research unit are:

* the DISPERSION21 model (also called DISPERSION 2.1) [ [http://www.smhi.se/foretag/m/dispersion_eng.htm DISPERSION 2.1 web page] ]
* the AirViro model [ [http://www.airviro.smhi.se/ AirViro web site] ]
* the MATCH model [ [http://www.smhi.se/sgn0106/if/meteorologi/match_publications.htm MATCH publications] ]
