11. Source code management
External access to FIELDEXTRA
currently limited to COSMO members.
it was decided to grant an external access to scientific community … initially for a single university to estimate what amount of support will be required.
the decision for full release was postponed to the next STC meeting

12. Source code management
COSMO Standards for Source Code Development – updates
technical changes from the CLM community: now the CLM-SUPTECH working group is responsible for coordinating developments for COSMO
new paragraph in Section 6.6 regarding the COSMO-CLM Test Suite
included the OpenACC Style Guide in Chapter 4.4
clarify the way how CLM people, who do not have access to ICON right now, can contribute to COSMO-ICON physics without being able to test ICON with their

13. Source code management
COSMO model documentation
STC recognizes it is vital to COSMO (both management and scientific purposes) to keep all the model documentation and web pages updated
Outdated (~2010) information on the operational settings
Limitted information on the suport and training capabilities
Missing recent information on PP/PT progress (e.g. PT ConSat4)
-> STC will take responsibility to correct this situation

14. NWP Test Suite
STC discussed a set-up of test runs:
series of forecast, each being reinitialized anew over;
one continuous hindcast run (preferable for STC);
series of forecasts, where the soil variable run freely and are not reinitialized
Further discussion was carried on at parallel session
(SPM: still no consensus on some issues)
Scientific aspects will be further discussed by the SMC
PT (or PP) proposal will be submitted (c/o F. Gofa, A. Montani, M. Milelli, R. Dumitrache, A. Iriza, U. Schättler)

15. COSMO activity proposals for 2018-2019
ISDA (International Symposium On Data Assimilation), March 5-9, 2018
Suport of parallel phase with dycore versions in FORTRAN/C++

16. COSMO activity proposals for 2018-2019
ISDA (International Symposium On Data Assimilation),
March 5-9, 2018
previous three ISDA attracted around 200 participants
ISDA is organized by DWD and the HErZ branch on DA at LMU Munich in collaboration with
COSMO consortium (2014),
RIKEN institute in Japan (2015)
University of Reading (2016)
ISDA 2018 in Munich on March 5-9 expect between 120 and 200 participants
COSMO will suport invited speakers and young scientists

17. COSMO activity proposals for 2018-2019
Request for support of parallel phase with dycore versions in FORTRAN and C++ by MeteoSwiss
PP POMPA development for hybrid architectures (NVIDIA GPU, multicore x86 CPUs) is being integrated into the official COSMO version.
On 34th meeting, STC decided to conduct the parallel phase with both Fortran and C++ dycores retained until Sept 2017
PT EDP2 (WG6) proposition to extend the parallel phase by two years and to reevaluate its necessity in two years' timeframe
Granted (after modification) activity proposal to ensure funding for updates, training, support of both CPU and GPU versions

18. Next ICON / ICON-ART Training in Langen from 16 to 20 April 2018
Update on ICON licensing/
agreement DWD – MPI-M
: ICON SCIENTIFIC license (institutional)
Institutional license because of ECMWF license for IFS physics

xx.xx.2017: ICON SCIENTIFIC license (individual) ready (provided by MPI-M).
ICON code provided by MPI-M
xx.xx.2018: ICON official duty license (institutional) ready (provided by DWD).
Free for NHMS from COSMO partners
ICON code provided by DWD
xx.xx.2019: ICON official duty license (institutional) ready (provided by DWD).
Free for NHMS from development countries
With license fee (shared between DWD, MPI-M, ECMWF) for NHMS from developed countries

20. CGM STC/WG reorganization
Goal: reduce bureaucracy, increase productivity
Reduction of reporting during STC, most of the information is being presented during plenary sessions
Increase presence of SPM in the WG sessions to overlook scientific issues
Above require slight modifications in the WG/STC agendas and stricter requirements for submitting in advance proposals/documents for STC evaluation.
Some decisions may require earlier SMC approval but decisions can be reached remotely be .
