Air quality researchers use Mars as a laboratory in new project

MeteorologyAtmospheric Remote SensingAir Quality

Dust from sandstorms in desert areas degrades air quality even over long distances and can cause other problems for society as well. At the same time, scientists find it difficult to study and describe these processes with sufficient accuracy, without interference from other aerosols. But now they …

New methodology for calculating air pollution provides national exposure and health data for Sweden

MeteorologyAir Quality

Polluted air affects your health - especially if you are a child, elderly or belong to a risk group. At SMHI, researchers and air quality experts are now developing a new methodology for calculating how much air pollution the population is exposed to, both now and in the future, in cities and in …

Urban environment design reduces local heat islands

MeteorologyClimateAir Quality

A study examining heat in urban environments has shown that good physical planning reduces the urban heat island effect, making it easier to deal with heatwaves. Knowledge from research on heat in cities from the Hazard Support project has now been compiled at smhi.se.

Research provides new knowledge for local climate adaptation measures

MeteorologyHydrologyOceanographyClimateAir Quality

A changed climate with more extreme weather involves a heightened risk of natural hazards if society is not prepared for the new conditions. How do municipalities and other stakeholders use new research in their planning? SMHI and SEI have examined how research can be designed to meet users’ needs.

New project studies air pollutants from forest fires

MeteorologyClimateAir Quality

There have been several major forest fires in the large, forested areas of the northern hemisphere in recent years, and these have led to an increase in air pollutants which affect human health. Researchers are now investigating how a changed climate with rising temperatures and more extreme …

Measuring wind with the Aeolus research satellite

MeteorologyAtmospheric Remote Sensing

Understanding the wind in the atmosphere is very important for both weather forecasts and climate models. In August 2018 the satellite Aeolus was therefore launched to test a completely new way of measuring winds over the entire world using a very sophisticated Doppler wind lidar instrument. The …

Earlier spring peak of ground level ozone positive for vegetation

MeteorologyClimateAir Quality

Changes in levels of ground level ozone have been analysed by researchers in a multi-year research programme. They can now ascertain that there is a trend towards a narrower overlap between the year’s maximal level of ground level ozone and the early growth period, which is positive.
