  1. COSMO Scientific Management Committee Meeting 5-6 February 2019, Offenbach a. M., Germany Discussion points, some useful info, etc. (dmiitrii.mironov@dwd.de) COSMO SMC Meeting, 5-6 February 2019, Offenbach a. M., Germany

  2. 2. NWP Test Suite • COSMO-model version 5.05: results obtained so far, problems encountered, work to do, resources at ECMWF (Massimo, Flora, Uli) • NWP TS for COSMO: Andrea is at ECMWF, Ines takes over the job, etc. (Ines, all) • NWP TS for ICON-LAM: set-up (hindcast or/and series of forecasts, etc.), the need for ICON-LAM SP runs (cf. ICON global physics that is always DP), co-ordination of COSMO consortium and DWD-MPI activities, time line (all)

  3. 3. New COSMO versions, model documentation, common ICON-COSMO physics • New COSMO-model versions, presentations by Uli • From minutes of September 2018 SMC meeting (to refresh your memory) • POMPA: port of Assimilation and LHN (already in 2018) 5.05b • Radar forward operator (EMVORADO) (hopefully, in 2018) 5.05c • still needs some technical clean up and documentation • tests at DWD are ongoing • Higher order horizontal discretizations (by end of 2018) 5.05d • already available, see plans by WG2 • Mire parameterization 5.05d • Ground water runoff (by Linda Schlemmer, if port ready before end of 2018) 5.05d • Technical modifications from data assimilation [extension in the observation processing (tower data)] 5.05d • Urban module (tests in PT AEVUS are ongoing) 6.0 • Unification with CLM Version (work in progress) 6.0

  4. 3. (cont’d) New COSMO versions • From minutes of September 2018 SMC meeting • Moreover there are other technical issues • COSMO-EULAG: code and documentation available. Timeline for implementation will be discussed by SMC • Removal of coarse radiation grid (perhaps 5.06, work in progress) • Optimization of copy-in/copy-out (perhaps 5.06) • Use of CLAW directives to optimize physical parameterizations for GPU • GPU Port for Tiedtke-Bechtold convection

  5. 3. (cont’d) Mire parameterization • Results from recent parallel experiment performed by Jürgen Helmert (presented by Dmitrii) here • Discussion

  6. 3. (cont’d) Model documentation • “Supplements” to our “core documentation” are currently placed under “miscellaneous” but a better solution is desired (issue raised by Uli Blahak) • Documentation of Matthias and Guenther’s (Zängl) extensions implemented into turbulence scheme (Matthias) • Single-column model documentation (Matthias) • DOI for COSMO Technical Report and Newsletters (Dmitrii) • Improvements re. COSMO Newsletters (recall discussion at September 2018 SMC meeting) • Model documentation in view of the advent of ICON-LAM. Any comments, thoughts, suggestions?

  7. 3. (cont’d) DOI for COSMO publications • Assign DOIs via DWD • DWD is already a member of DataCite • We (WG6, NMA colleagues) get DOIs using the DWD membership, extra password needed (DWD should agree, DM finds out shortly) • Landing page is that of the DWD library (access through COSMO web via link) • Publications are “frozen” once DOI is assigned • Assign DOIs via one of the COSMO members (e.g. NMA) • Must be a legal entityto become a member of DataCite (or other agency) • Landing page is at the COSMO web • COSMO folks can do small editorial changes in published texts • Life expectancy of COSMO web?

  39. 20. (cont’d) Thoughts by Andrzej W. (email of 8 September 2018 following discussions at the SMC meeting in St. Petersburg) I would like to add some thoughts on the COSMO activities in the frame of time 2019-2020+ in relation to the recent COSMO Science Plan 2015-2020. In the SP we mention on several occasions about the potential capabilities of COSMO model (and implicitly ICON) for a high resolution deterministic weather forecasting going down to 500m spatial resolution, which was then planned for an operational work around 2020. From my knowledge there were so far just several experiments at the resolution below 1000m (even down to ~100m resolution) by using both ICON-LAM and COSMO-EULAG. So I think it is about a time to explore these areas in a more coordinated way. If possible I would like you to discuss possibility for starting such an effort. My idea would be to stir some kind of collaborative project between teams working with ICON-LAM and COSMO-EULAG in the frame of WG2 (maybe also in collaboration with WG3x, WG5, etc.) . As you have noticed all the development for COSMO-EULAG should be finalized around sept 2019 and then more resources should be available to perform additional/new tasks.

  40. 20. (cont’d) Thoughts by Andrzej W. My idea is to prepare at least one year PT project which would explore capabilities of our models (ICON-LAM/COSMO-EULAG) to perform NWP at the spatial resolution below 1000m (500m or even below). The tests may include real time or more idealistic simulations, including areas with steep topography, coastal or maybe even urban environments. I see the outcome from this project would provide us more information about model/s: - NWP verification scores in the winter and summer time conditions - changes in computational performance for the different resolutions - stability limits for different environmental conditions (e.g. max time step,   parameters controlling the physical parametrizations, etc.) - ability to represent severe phenomena related to deep moist convection/wind - identification of deficiencies in physics and numerics which would constitute   a base for further actions to be planned in the science plan 2020-2025. Of course above are only my personal thoughts, you can feel free to discuss these issues within SMC/WGs and come up with your own plan.
