Atmosphere COSMO/CCLM Community Land Model VEG3D COSMO CLM-Community TERRA (+ sub-modules) Possible future directions: Stay with TERRA and ignore alternative LSMs? Option for several LSMs? Choose one LSM based on intercomparison of performances?

TERRA Person/institution in charge Description of development Version Status B. Ahrens (Uni Frankfurt) New numerics for the Richards equation (necessary for multiple soil horizons and moving water tables) Already implemented in TERRA stand-alone; will be tested in COSMO-CLM Implementation in TERRA stand-alone in its final testing phase; implementation in COSMO-CLM in 2012 Carbon cycle Will be implemented first in TERRA stand-alone to be finished June 2012 (stand-alone version) Dynamic vegetation To be started in 2012 S. Schubert (PIK) Urban scheme BEP (Martilli et al. 2002) ? K. Trusilova (DWD) Urban scheme TEB (Masson 2001) COSMO-CLM v? End 2012 H. Wouters (KU Leuven) urban parameterization into TERRA_ML (this includes thermal roughness lengths parametrization with the help of new stability functions momentum and heat. Albedo, emissivity and momentum roughness length will be derived from satellite data to represent urban surfaces) TERRA stand-alone 4.11 Early 2013 J. Volkholz (PIK) River routing model
