CIRA Interests in COSMOCIRA Interests in COSMOAccording to CIRA background, main interests are in Numerical and Physical Modelling (WG2 and WG3)

Example of possible contribution activities for the next year (after ourparticipation to this meeting) :

WG2-Collaboration in testing of different physical interfaces in LM_Z-Contribution to R-K case studies-Contribution to evaluation of overall performances of LM_Z

WG3-Parameters tuning for validation of new code developments (e.g. convection- turbulence schemes)-Performing sensitivity studies in order to investigate model deficiencies in the precipitation forecast

Available manpower for 2006: 2 FTE

CIRA contribution (including other possible activities) will be coordinated and discussed with Italian representatives in COSMO

CIRA will request to the COSMO STC (via UGM) the LM code
