Science Plan and SPM report COSMO General Meeting, 9 September 2010

2 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) спасибо большое всем! Thank all of you! Lots of interesting talks and many promising results. The Priority Projects are reaching important milestones. – COSMO-DE-EPS becomes pre- operational shortly! Priority Projects (and also some of the Working Groups) are building up common know-how, and the project members obviously enjoy to reach common goals together. At last, COSMO starts to become a large family, and does indeed develop a common spirit.

3 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Science Plan What has been done since the last General Meeting: submitted SP for an external review (SRNWP ETs and COSMO-CLM; 7 reviews obtained) addressed (most of the) questions, comments and feedback by reviewers; did some structural and many editorial changes main changes in content since last GM: increased visibility of COSMO-CLM and COSMO-ART to reflect their rising importance added HP(2)C / PP POMPA issues Steering Committee approved the SP last Monday

4 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Science Plan : Summary Goal: Operational forecasting of mesoscale weather Strategy Ensemble prediction system for the convective scale Data assimilation system for the convective scale Extension of environmental prediction capabilities Verification and validation tool for the convective scale Intermediate resolution COSMO version for BCs Usage of massively parallel computer platforms Intensified collaboration

5 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Science Plan: Next steps distribution to COSMO (and beyond) asap information of directors publication on COSMO web-site (public part!) update / next revision of Science Plan in roughly two years  Science Plan

6 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Science Plan: Consequences Establishment of a new Working Group “Predictability and Ensemble Methods” (WG 7) Working Group “Interpretation and Applications” (WG 4) “Interpretation”: stronger focus on forecaster issues (‘how to use the models’) and case studies (forecasters as very demanding and candid users of the models) “Applications”: explicit inclusion of post-processing methods (calibration, MOS, …; fieldextra) invitation of COSMO-ART (Bernhard Vogel) and new DWD COSMO Coordinator (Uli Blahak) to the Scientific Management Committee

7 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Source code management for ‘COSMO Software’ Motivation: growing amount of software growing community contributing to the development of the software  ‘COSMO Software’ A successful source code management needs  scientific planning  technical requirements

8 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) ‘COSMO software’ Technical requirements for software to become ‘COSMO software’: portable documented (internal & external) supported Consequence for software to remain ‘COSMO software’: continuous and long-term maintenance

9 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) ‘COSMO software’ COSMO model, including forecast model data assimilation system (nudging, ETKF filter) provision of operational external parameters (Note: EXTPAR will only be distributed for R&D and ‘as is’) INT2LM fieldextra (COSMO post-processing tool) VERSUS (COSMO verification tool)

10 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Source code management for ‘COSMO Software’ Scientific planning clear strategy Science Plan Priority Projects and Priority Tasks yearly Work Plans clear responsibilities (inside COSMO) and focal points (outside of the consortium (e.g., COSMO-CLM, COSMO- ART))

11 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Source code management for ‘COSMO Software’ Scientific Management Committee (SMC) is responsible for the scientific planning related to (and needed for) the source code management: release planning and priority setting definition of responsibilities (in accordance with resource planning by STC) and focal points (in accordance with respective planning by e.g., COSMO-CLM and COSMO- ART) This transfers substantial responsibility (mainly) from Ulrich Schättler / DWD to the SMC / COSMO!

12 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Source code management for ‘COSMO Software’ Technical requirements clear rules coding standards documentation standards quality control standards (test experiments, verification) transparency (  ‘redmine’, ‘codendi’, …) release planning setting of priorities tbd by WG 6; approval by STC in March 2011

13 Science Plan and SPM report | COSMO General Meeting, 9 September 2010, Moscow Marco Arpagaus (marco.arpagaus [at] meteoswiss.ch) Source code management for ‘COSMO Software’ Technical Advisory Group (TAG) is responsible that technical requirements are met: definition of rules (and supervision of their implementation) technical release planning and priority setting (in accordance with the scientific planning of the Scientific Management Committee) Chief software administrators for COSMO, fieldextra, and VERSUS are responsible for implementation of decisions by TAG. tbd by WG 6; approval by STC in March 2011
