During the Conference and Young Researchers Workshop, Sarah explains what her project is all about.
JULES is a global land surface model. It simulates vegetation, soil and transfer of energy and water, from the atmosphere, into and out of the land surface, and through the soil.
JULES simulates freezing and thawing and so we can use it to simulate permafrost across the whole globe.
If we run the model into the future, using atmospheric data from a climate model, we can show how the permafrost area decreases with future climate warming.
This case is a low-emissions scenario, and we still see a significant loss of permafrost.
I have added in new processes to improve the model. These include a representation of moss cover on top of the soil, and organic matter in the soil, which provide thermal insulation.
We are also simulating deeper soil, to make the temperature dynamics more realistic.
