8. 24.-26.09.20035th General COSMO Meeting --- Langen, Germany8 Software in a β-Version State IFS2LM –Can be used from int2lm_030224 (available on DWD´s ftp-server) –is used for the COSMO_LEPS –and now also for aLMo –Open problem: How to interpolate cloud ice from ECMWF?

9. 24.-26.09.20035th General COSMO Meeting --- Langen, Germany9 Software in a β-Version State LM2LM –can be used from int2lm_030520 (on ftp-server) –has been tested and debugged by DWD (FE25), IfT and the German Military Service –is used by DWD for producing initial and boundary conditions for very high resolution LM (LMK) –is used by ARPA for several projects INT2LM still not available

10. 24.-26.09.20035th General COSMO Meeting --- Langen, Germany10 Software in a β-Version State Nesting version of LM –is tested by HNMS and by ARPA Piedmonte –some technical problems could be solved (runs with artificial data) –remaining problems sequential version is not running assessment of interpolation and feedback routines relaxation of boundary and external data into the nests –this version is based on an old LM version (2.1)

11. 24.-26.09.20035th General COSMO Meeting --- Langen, Germany11 COSMO Software Operational Software –Official Software for which support is given by Source Code Administrator(s) and developers β-Version Software –Software under development for which limited support is given by the developers Software Tools for Exchange –Software that is provided by the developers without „official“ support

12. 24.-26.09.20035th General COSMO Meeting --- Langen, Germany12 COSMO Software (cont.) List of operational software will be updated (regularly or on request) Request to add programs to the operational software could be given to the SSC, SPM or the group of the WPCs For example: Soil Moisture „Analysis“; SST, Snow Analysis,...

13. 24.-26.09.20035th General COSMO Meeting --- Langen, Germany13 Working Group on Code Optimization and Portability This group met once in Zürich with participants from MCH, DWD and CSCS Platform to exchange and centralize information Should promote expertise on ALL computer platforms Guarantees solutions for „portable optimizations“ See the Web Site: Link from description of WP 6.1.2
