WG Coordinator: Ulrich Schättler

2. 5th General COSMO Meeting --- Langen, Germany
The Work Packages
6.1: Operational implementations
6.2: Running the web site
6.3: Restructuring of documentation
6.4: Operational coding of the INT2LM
6.5: Operational coding of the nesting Version
6.6: Restructuring of diagnostic output

3. 6.1: Operational Implementations
Updates of programs and documentations (see next presentation)
Code opimization and portability
A working group (DWD, MCH, CSCS) has been formed (met once)
Guidelines for the work have been setup
Most important: Portable Optimization
Define the first Reference Version
The Reference Version is LM 3.1
Install test cases and produce „Reference Output“
3 test cases have been selected for which Reference Output is available
there still is no consent about the Update Procedure
Software Engineering Guidelines

6.2: Running the Web Site
Maintaining, updating (and mirroring) the Web Site
Define a template for describing the operational applications
Descriptions of the operational applications on the public domain of the Web Site
see next presentation
Update histories of the programs
(Internal and external) description of WG 6
Software tools for exchange within COSMO
Several tools are available: field_extra, MakeAOF, grIns
On the private pages of the Web: Software/Utilities

5. 6.3: Restructuring of Documentation
Numerics and Dynamics
Physical Parameterizations
Data Assimilation
Implementation Documentation
User Guide (but not web based)
(Web based) Quick Reference Guide

6. 6.4: Operational coding of INT2LM
No general interpolation program INT2LM ready up to now.
But different components now as seriously tested β-versions:
IFS2LM as version int2lm_030224
LM2LM as version lm2lm_030520
GME2LM Version 1.17 as „official“ version

7. 6.5: Operational coding of the nesting version
The nesting version is tested by HNMS and now also by ARPA Piedmonte (for Olympic Winter Games 2006)
Some technical problems could be solved
But there are still open problems (see next presentation)
Operational version is not in sight

8. 6.6: Restructuring of diagnostic output
The diagnosis for subdomains (YUPRDIAG) and the differences of forecast fields to the boundaries (YUPRDIFF) have been eliminated in Version 3.5 (because they have not been used)
The grid point output has been restructured to include cloud ice; the format of long and short output has been changed.
See (new) User Guide about the changes in the NAMELIST input

: The Rest
The Grib code (clean implementation; external Grib table)
no actions have been taken
Proposal for a set-up of a file-based data-assimilation suite
still has to be written
Towards ISO 9000
DWD is about to start with ISO activities
Dieter Frühwald will inform the SSC
