Task 4: Revision of TERRA and the associated look-up tables
• Gather and integrate tested developments of TERRA in official COSMO code - V4.11 2009/11/30
• Define a consolidated set of look-up tables EXTPAR (ECOCLIMAP, GLOBCOVER)
• Find and validate an ‘optimal’ reference configuration of TERRA, using the external parameters developed within task 3.2 with the consolidated look-up tables
Benefit: Unification of physics in TERRA standalone, GME, and COSMO Appropriate configuration for all climate regions

• Results from GME experiments suggest that soil moisture analysis (SMA) has a large impact on the results
• Difficulties for parameterization changes to outperform SMA
• Impact of model initialisation is important
• Improved post-processing required to avoid experiment initialisation from large-scale models
• Benefit: Unified land-surface scheme for global, regional, and stand-alone application
