COSMO priority project, 09.2008 – 09.2011
Goals
• Facilitate access to soil/surface observations
• Consolidate tools of general interest:• externalized TERRA module • software for generation of external parameters
• Consolidate and extend external parameters database
• Find and validate an optimal configuration of TERRA
• Revision of snow analysis and snow model
• Deployment of urban module developed in Switzerland
• Consolidate parameterization of land surface heterogeneity

What has been achieved?
Do we need a COCOLOBOC ?
PP COLOBOC, Final Report | COSMO GM, 5-8 September 2011, Roma
COLOBOC, task 0
Observation sets for model validation and development
• New instruments at PayerneMeasurement of turbulence @ 10m, in activity since spring 2009.Soil moisture and temperature kept after end of SwissSMEX
• Data exchange action within SRNWP
5 PP COLOBOC, Final Report | COSMO GM, 5-8 September 2011, Roma
• Goal: convenient access to recent operational high quality observations, representative for different climate and different type of soils
• Action started in October 2009 with an official letter sent to a selection of NMS directors.
• Agreement within the C-SRNWP Programme of EUMETNET :“I would like to emphasise that the data would be provided ONLY for the C-SRNWP members (particularly to the Expert Team members) with a significant time-lag after the observational time and for research purposes only.”
• Resources from DWD (C.Heret, F.Beyrich), HNMS (T.Andreadis) and MCH (JM.Bettems) as contribution to the COLOBOC project.
• Support from C-SRNWP coordinator (András Horányi) and from chair of SRNWP ET Soil and Surface (JF.Mahfouf)

Task 3.1: Document available data
Task 3.2: Consolidate and extend database
Add seasonal climatology of vegetation characteristics. Add parameters for subscale orography. Add parameters for orographic radiation correction. Add parameters for urban fraction. Add parameters for deep soil temperature. Add parameters for FLake. Provide alternative sets of soil types in Europe.

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

PP COLOBOC, Final Report | COSMO GM, 5-8 September 2011, Roma
Priority project COLOBOCFinal status (ok, finalized till end 2011, not all goals reached)
T0. Observation sets for model validation and development > new instruments at Payerne> SRNWP data pool action, with 9 sites> coordination transferred to WG3b, resources guaranteed
T1. Externalized TERRA module> consolidated package and documentation available on COSMO web site (based on COSMO 4.13)> not supported, open question in WG3b
T2. Software for generation of external parameters> consolidated software EXTPAR v1.5> software and documentation are available (software available at DWD, soon on COSMO web site)> web portal soon operational
T3. External parameters > Documentation of data sets available> Consolidated data set, with 15 new parameters
T4. TERRA improvements > Implementation of TERRA developments into COSMO V4.11 2009/11/30> Definition of the consolidated set of look-up tables in EXTPAR > Experiments at MeteoSwiss and DWD showed mixed, neutral impact on verification scores> Physically more realistic, basis for further developments
PP COLOBOC, Final Report | COSMO GM, 5-8 September 2011, Roma
Priority project COLOBOCFinal status (ok, finalized till end 2011, not all goals reached)
T5.1. Improved snow model> revised parameterization of snow albedo (incl. ageing)> revised parameterization of partial snow cover (height instead of snow water equivalent based)> proposition for a new parameterization of old snow density> new multi-layers snow model implemented in COSMO 4.11> still some stability issues for very shallow snow layers, corrections being investigated> official release, tested and documented, planned for Q2 2012
T5.2. Snow analysis> unified snow analysis software (MCH modifications merged in official sfcana) > altitudinal interpolation not available, temporal stability of analysis may be an issue
T6. Urban module BEP> code and documentation available at MeteoSwiss (based on COSMO 4.7)> not supported, open question in WG3b
T7. Parameterization of surface heterogeneities with the tile/mosaic approach > tile and mosaic implemented in COSMO 4.16> user configurable, dynamic tiles for snow supporting surface types> consolidated and official release planned for Q2 2012
