1 Federal Department of Home Affairs FDHA Federal Office of Meteorology and Climatology MeteoSwiss News from the consortium Swiss COSMO User Workshop 1st November 2012

2 COSMO users for NWP by 2012 Members of Consortium COSMO are the national meteorological services 2

4 COSMO-ART users IMK-IFU: Dust storms over China IMK-AAF: Pollen as IN IMK-ASF: Troposphere-Stratosphere Exchange EMPA, Switzerland: Aqueous chemistry, Validation Rosshydromet, Russia: Air quality above Moscow, Vegetation Fires NCMS, United Arabic Emirates UAE: Dust storm forecast Georgia Tec, USA: Aerosols and cloud formation Carnegie Mellon, USA: Soot impact on regional climate Meteoswiss, Switzerland: Operational pollen forecast DWD, Germany: Forecast of pollen, mineral dust and volcanic ash National Observatory, Greece: Forest fires, air quality Weather service of Romania: Air quality BTU Cottbus, Germany 4

5 Source code management Motivation Need for clearer rules with the increase of users. Easier software maintenance and quality control. Insurance of a continued quality of the Software concerning design implementation (coding) documentation testing Necessary for COSMO to protect the many operational uses often related to critical applications 5

6 Source code management Development process Reference Version of The Software Released Version of The Software Monitor: Somethings going wrong? Software incomplete? New scientific breakthroughs? Testing by special users: COSMO Test Users NWP Test Suite The Idea (and first development) Development / Test Versions of The Software First Management Decision: inline with planning? needs resources? The Implementation (into an official version) Second Management Decision: technical requirements fulfilled? (Technical Test Suite) meteorological tests ok? documentation available? The Development (of a private version) 6

7 Source code management Coordination with CLM and ART communities Coordination with CLM and ART communities through participation in their coordinators in the COSMO Scientific Management Committee Policy defined by the COSMO Steering Committee to consider the input of CLM and ART for reference versions The STC confirms the importance of these three COSMO applications and the fruitful cooperation between the respective communities. For accomplishing this goal it stresses in particular the key role of the common reference COSMO code and its long-term stability. Consequently, the ART and CLM communities take part in the source code management process via scientific cooperation with the respective Working Groups and via their representatives in the SMC. The STC will thoroughly consider their opinions while making the final decisions on the reference software. For functions which are mission critical for CLM or ART, it will be open for implementing them with ifdefs. 7
