  1. CommunityActivities and Plans A.Will (BTU Cottbus) and the CLM-Community

  2. GCM RCM WPM • Intended use of the Climate mode • Simulation of climate change in different regions of the world. • Quantification and reduction of ucertainties of climate change (IPCC 2001/2006) • Relevance for GCMs • Analysis of the relevance of nonhydrostatic effects local phenomena and of microphysics for climate dynamics. Relevance for NWP • detection of model deficiencies not visible on small time scales • Independent evaluation without influence of initial conditions and data assimilation

  3. Developed by the CLM-Community in cooperation with the German weather service (1) different model versions for NWP and RCM (2) Climate mode not overall tested.

  5. Developed by the CLM-Community in cooperation with the German weather service • Aims of the CLM CommunityFurther development of the COSMO-CLM to be a regional earth system modelQuantification and Reduction of Model UncertaintiesEfficient Use of Computational RessourcesPreparation and Conduction of Consortial Scenario Runs

  6. Developed by the CLM-Community in cooperation with the German weather service Main Projects in the last year • PrEProcessor (PEP) for External Fields (a) • Unified Preprocessor int2lm2 (a) • Veg3D fully coupled with COSMO-CLM_4 a • Basic Sensitivity Studies (a) • Consortial runs successfully finished a • Coupling with Com. Land Model (CLM) • Improvements of TERRA_ML • Aerosol-Cloud Interaction • Standard Postprocessor CLM Model system Features of int2lm_2 Preprocessor

  7. Developed by the CLM-Community in cooperation with the German weather service PrEProcessor (PEP) for external fields

  8. Developed by the CLM-Community in cooperation with the German weather service PrEProcessor (PEP) for external fields

  9. Developed by the CLM-Community in cooperation with the German weather service int2clm + int2lm Int2lm2 Interpolation to LM/CLM grid

  10. VEG3D is fully coupled with CLM version 4.0 and is being evaluated Main differences between TERRA_LM and VEG3D: Standard soil model of CLM (TERRA_LM) uses the surface temperature for transpiration calculation <-> VEG3D has an explicit vegetation layer (“big leaf concept”) and simulates a vegetation temperature Runoff from soil layers is organized differently in both models Different formulation of water transport in soil and snow treatment Additional parameters: Land use => taken from the PEP Soil parameters => additional file in CLM code Developed by the CLM-Community in cooperation with the German weather service 1. Implementation of soil-vegetation model VEG3DCathérine Meißner and Gerd Schädler, University / Research Center Karlsruhe First results: • Annual evapotranspiration sum more homogenous in VEG3D which agrees better with measurements (figures) • Influence on annual preciptation in the range of 100 – 200 mm OBSERVATIONS TERRA_ML Veg3D mm
