  1. Ulrich Schättler Status of the COSMO-Model Package

  2. Current Status Several components are belonging to the COSMO-Model; new components are on their way (chemistry) into the official source code Actual Versions are COSMO-Model 4.5 and INT2LM 1.8 Officially distributed COSMO-Model 4.2 and INT2LM 1.7 10th COSMO General Meeting - Krakow, Poland

  3. Source Code Administration Starting point last autumn: COSMO-Model 4.0 including: Runge-Kutta dynamics; high-resolution applications Climate mode functionality INT2LM 1.6: on the way to full climate mode functionality Plans for the year 2007/08: Consolidation of the schemes Finish INT2LM to work fully in climate mode Include new components (2-moment microphysics, COSMO-ART) 10th COSMO General Meeting - Krakow, Poland

  4. Source Code Administration COSMO-Model 4.1/4.2: (05.12.07) Bug fixes for reproducibility (DA, RK, SL-adv) Calculation of supercell detection indices Changes in the gust parameterization Brightband detection in radar data COSMO-Model 4.3: (22.02.08) Changed computation of 2m Temperature 10th COSMO General Meeting - Krakow, Poland

  5. Source Code Administration COSMO-Model 4.4: (16.07.08) Changed treatment of convective cloud condensate in the Tiedtke convection scheme Changed structure of advection routines in the RK dynamics for a better optimization Optimizations for a better vectorization COSMO-Model 4.5: (05.09.08) Reading observations from a NetCDF file Correction for computing reference pressure on half levels Introduction of the SSO scheme Implemented alternative reference atmosphere Further optimizations for RK dynamics and vectorization 10th COSMO General Meeting - Krakow, Poland

  6. Source Code Administration INT2LM 1.7 (23.11.07) Additional humidity splitting after balancing / filtering pp Implemented several options for treatment of deep-soil and plant characteristics (for CCLM) Implemented „Ensemble Mode“ to provide different boundary conditions to the COSMO-Model INT2LM 1.8 (26.05.08) Optimizations for vectorization Interpolation of qr and qs from the GME grid Read new external parameters (for SSO, topographical corrections) Adaptations for climate mode 10th COSMO General Meeting - Krakow, Poland

  7. Source Code Administration Officially tested and distributed in Dec 2007: COSMO-Model 4.2 and INT2LM 1.7 Development version distributed in March 2008 COSMO-Model 4.3 Development versions (not distributed): COSMO-Model 4.4, 4.5 and INT2LM 1.8 Work is going on to implement 2-moment microphysics COSMO-ART Official release in autumn 2008! 10th COSMO General Meeting - Krakow, Poland

  8. (New) WG 6 Activities Implementation of a Source Code Task Force within WG 6 to discuss development strategies (modularity of code; re-use of components in other programs) discuss development of other programs (postprocessing) discuss contents of COSMO-Model package discuss contents of COSMO Software Responsible: Source Code Administrator + members from other institutes 10th COSMO General Meeting - Krakow, Poland

  9. (New) WG 6 Activities Re-activate a former WG 6 task: Code Optimization and Portability discuss and test implementation strategies for different processor architectures discuss and test implementation strategies for hybrid parallelization observe developments in processor architectures (multi-core chips) Responsible: Uli Schättler 10th COSMO General Meeting - Krakow, Poland

  10. (New) WG 6 Activities Set up a new WG 6 task: Grib Issues a forum to discuss various Grib (1) problems discuss use and introduction of Grib 2 in COSMO Responsible: ? 10th COSMO General Meeting - Krakow, Poland

  11. THE END Thank you for your Attention 10th COSMO General Meeting - Krakow, Poland
