Climate change makes reducing eutrophication even more important


Significant reductions in nutrient discharges from the land will result in reduced eutrophication in the Baltic Sea and a better marine environment by 2100 – regardless of how serious the effects of climate change are. These are the findings of research carried out by Stockholm University’s Baltic …

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.

New research gives an indication of the amount of summer precipitation in Northern Europe

MeteorologyClimateRossby Centre

Researchers at SMHI have found a teleconnection between the atmospheric conditions over the subtropical Pacific during spring and summer precipitation in the Northern Europe. This discovery creates the prerequisite for a simple, yet relatively accurate, estimate of summer precipitation several …
