Satellite measurements show hidden water content of snow

Hydrology

As spring arrives, many people are generally interested in the snow vanishing. Others are more interested in the water that is stored in the snow layer. Satellite measurements can show the extent and water content of the snow coverage, and where it will melt.

Satellite data provide insight into melting Arctic ice

Meteorology

In September 2012, the smallest ice spread to date in the Arctic was recorded. 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.

Higher temperatures affect intensive rain showers

MeteorologyClimate

Higher temperatures affect the conditions for cloud formation and rainfall. Heavy rain showers, such as summer thunderstorms, are influenced more by temperature than rain from larger widespread rain systems. Heavy rain has far-reaching consequences for society, and these could worsen at higher …

New way of predicting ice on wind turbines

Meteorology

As wind turbines become an increasingly important source of energy, there is a growing need to better predict when ice forms on them and prevents electricity from being produced. A research project at SMHI has developed new methods for projecting ice formation on wind turbines.

New climatology on clouds and radiation from weather satellite data

Meteorology

The properties and distribution of clouds around the globe are important to climate research. There is now a 28-year compilation of clouds and radiation – a cloud climatology – based on data from polar satellites.

New planning tool for climate adaptation in cities

HydrologyClimate

A changing climate places great pressure on society, and creates many new challenges. To make city planning easier, a planning tool has been developed to support climate adaptation of cities and regions in Europe.

Ocean pH value decreasing

Oceanography

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.

How does the climate in the Baltic Sea vary?

Oceanography

How has the climate in the Baltic Sea varied over the past 150 years? How will it develop up to the year 2100? A new research project will analyse how the climate in the Baltic Sea has varied since 1850 and simulate future scenarios for the Baltic Sea.

New special issue of AMBIO: future state of the Baltic Sea marine environment

Oceanography

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.
