SMHI expands European archive of climate simulations

Together with eight subcontractors, SMHI will expand Copernicus’ archive of detailed regional climate simulations for Europe. This will allow for comparisons of how different emission levels affect climate change.

“This larger archive of climate simulations is based on different emission scenarios. We can compare how the climate would change as a result of large quantities of greenhouse gas emissions. This means we are better able to predict the future, and it provides us with a better foundation for society when working with emissions reduction and climate adaptation,” says Erik Kjellström, researcher and head of the Rossby Centre at SMHI.

Detailed regional material

The detailed regional simulations are based on global simulations from the large-scale climate modelling projects CMIP5 and CMIP6.

The complete collection of regional simulations will be entered into Copernicus’ data services as part of the European Programme for Earth Observation. This will pave the way for many future products and services within the Copernicus Climate Change Service.

“For us as researchers, a larger archive will provide a better opportunity to analyse future climate change scenarios. We will also be able to look into any uncertainties in the development,” Erik Kjellström explains.

Four year project

The project will continue up to 2021. The regional simulations are made in accordance with international standards developed within the global CORDEX network. SMHI is the principal party, with collaborators including institutes and universities from Denmark, France, Italy, the Netherlands, Switzerland, the United Kingdom and Germany.
