Ice and Climate: Regional modelling

Regional Modelling

More than half of the current global sea level rise is attributed to the mass loss of glaciers, ice caps and ice sheets. Their surface mass budget reacts sensitively to changes in global climate. Given the vast glaciarized area in the world, in situ observations, however crucial, can only provide limited insight in the total surface mass budget of glaciers and ice sheets. Surface mass balance models provide the means to dynamically upscale these local observations.

Since the mid-1990's, the Institute for Marine and Atmospheric Research of Utrecht University (UU/IMAU), in cooperation with the Royal Netherlands Meteorological Institute (KNMI), has been using and improving the Regional Atmospheric Climate Model RACMO to study the mass budget of the ice sheets of Greenland and Antarctica and several smaller ice caps. In conjunction, a firn model has been developed for detailed studies on firn processes, but also in support of laser and radar altimetry observations.

Data

RACMO and the firn model have both been applied to different glaciated regions of the world. Most recent model output is freely available upon request. Follow the appropriate links to see what is available. Information on how to obtain data can be found at top right. The available studies cover the following regions:
- Antarctica
- Greenland
- Other ice caps such as the Canadian Arctic and Patagonian Ice fields.
