# Data of the Next Generation Earth Modelling Systems project
nextGEMS is a collaborative European project. Funded by the EU’s Horizon 2020 programme, it will tap expertise from fourteen European Nations to develop two next generation (storm-resolving) Earth-system Models. 
Through breakthroughs in simulation realism, these models will allow us to understand and reliably quantify how the climate will change on a global and regional scale,
and how the weather, including its extreme events, will look like in the future. 
See further details at https://nextgems-h2020.eu/ and https://cordis.europa.eu/project/id/101003470.
