Modelling of water resources

Modelling of water resources

In this project funded by the Greenland Research Council, Asiaq will - in cooperation with The Danish Meteorological Institute - evaluate DMI’s regional climate model HIRHAM5 by comparing model output with existing, independent measurements of water resources from catchments without glaciers in south Greenland.

In recent years the use of regional climate models has increased considerable; both to give information about the current climate in areas, where no measurements exist and to predict the future climate. The model output is used for various purposes within planning and research. In Greenland, research has focused on estimating the mass balance of the Greenland Ice Sheet. Development of climate change adaptation strategies and evaluation of water resources for water supply and hydro power plants are examples for the use of regional climate model outputs in social planning.

When regional climate models are used it is essential to take into account the uncertainty of the model results. A number of studies have worked on verification of the regional climate models with regards to the mass balance of the Greenland Ice Sheet and a number of surface climate parameters. There has been less focus on for the ice-free part of Greenland. Especially, no project has so far evaluated the performance of the regional climate models with respect to predictions of the water resource for catchments without glaciers in Greenland.
