Description
SATellite based bio-geophysical parameter MAPping and aggregation modelling for CLIMATE models
Charlotte Bay Hasager is coordinator of the project.
Global climate change and weather forecasting is modelled by the HIRLAM (HIgh Resolution Limited Area Model) atmospheric flow model. This model is developed at the Danish Meteorological Institute in collaboration with other Nordic weather services. HIRLAM currently is used by weather services in many European countries. The exchanges of energy, water vapour and momentum between the land- and ocean surface and the large scale atmospheric circulation are very important dynamical processes in this type of model.
The SAT-MAP-CLIMATE project focus on development on parameterizations of the land surface fluxes mapped by Earth Observation data from satellites. The satellite information is used to cover the Danish land and sea with a high temporal and spatial resolution. Satellite based maps of land surface roughness, land- and sea surface temperatures and vegetation state will be area-averaged from a 30 m * 30 m resolution to the grid cell size of 5 km * 5 km in HIRLAM. The area-averaging is highly non-linear due to the turbulent physical processes involved. Thus the effective surface conditions cannot be obtained by simple averaging but only by a flow model taking horizontal advection into consideration.
Results of using improved surface boundary conditions in the HIRLAM model will be validated from wind and temperature data at synoptic weather stations and surface flux data from land- and ocean meteorological masts in Denmark. The possibility of surface flux climatology mapping will be evaluated. Further will a one-year climate prediction be carried out with the seasonal land surface effects included in the input conditions. This work is basic to improvements in global climate change predictions.
