Research for more accurate decisions and better information

Large areas of society are dependent on or influenced by the weather and water. Increased requirements with regard to the environment and a changed climate also provide new opportunities.

SMHI's research involves the development of tools and knowledge for many industries and areas of society. Mathematical calculation models are important tools which provide an integrated description of the processes on the ground, in the water and in the atmosphere.

An important aspect is also to develop methods to make better use of observations which form the basis of forecasting and developing scenarios and also to follow the development of the weather. Activities in the research department are based on extensive cooperation with other institutes and research establishments, both in Sweden and internationally.

The hidden water content of the snow layer

Satellite measurements can show the extent and water content of the snow coverage, and where it will melt.

Satellite data on melting Arctic ice

With data from satellites, scientists at SMHI have analysed changes in the atmosphere, and then compared the conditions for the ice melt in 2012 with 2007, the previous record low for ice spread.

Ocean pH value decreasing

A research project into ocean acidification has increased knowledge about conditions in the Baltic Sea and Kattegat-Skagerrak. When the pH value falls, the whole marine ecosystem is affected.

New Special issue of AMBIO about the Baltic Sea

The research project ECOSUPPORT focused on how the marine environment in the Baltic Sea might change due to the combined impact of climate change and nutrient discharge. Some of the project’s findings are presented in the new issue of AMBIO from the Royal Swedish Academy of Sciences.
