STC meeting Athens 28-29 November 2003 + SPM Internal Meetings STC meeting Athens 28-29 November 2003 + SPM Approval of the Activities/priorities Work Packages/Groups Coordinators meeting + Chairman Steering Committee + G. Doms + M.Rotach Geneve, 6-7 May 2004 Revision of ongoing activities Bologna, 9-10 September 2004 Last remarks about ongoing activities and preliminary planning of activities for the next year 03/01/2019

activities are ongoing General comments Data assimilation: activities are ongoing good advance (start) of activities related to SAT data assimilation no sensible improvement in radar data assimilation. Numerics: small group LM-Z common library “almost” ready LM-Z report planned for next year 03/01/2019

Nobody taking care of radiation in LM Applications: General comments Physics: Activities are ongoing; some delays. This WG still suffers from lack of human resources, although the situation has much improved since the last General Meeting. Difficulties in cooperaating from remote. Nobody taking care of radiation in LM Applications: COSMO-LEPS is running regularly. The system has been recently changed following results of probabilistic verification (to be shown later) A report to resume the results of the system validation is under planning. 03/01/2019

Other LM applications developed General comments Applications: Other LM applications developed Not yet a catalog of LM post-processing Guidelines for the use of bench forecasters and Collection of forecaster’s feed back A proposition will be elaborated by by P. Eckert, F. Sch ubiger, C. Cacciamani, B. Anger 03/01/2019

Still difficulties in pointing out common LM problems. General comments Verification: Still difficulties in pointing out common LM problems. Common verification package development is well addressed. Exchange of data is running; extension if this exchange also to other counties outside COSMO. 03/01/2019

Problems with the WEB-SITE now moved to Manno. General comments Implementation: From LM3.5 to LM3.12 Problems with the WEB-SITE now moved to Manno. Documentation still incomplete Newsletter No. 4 distributed. 03/01/2019

Quality of precipitation forecast Goals and perspectives for the past COSMO period (10/2003-09/2004) are: Goals : Consolidation, Documentation and Upgrade of the LM Quality of precipitation forecast Assessment of the 'realism' of forecasts Multi-national assement assesment of COSMO-LEPS products Assimilation of remote sensing data Application and Interpretation Statistical interpretation of high resolution forecasts Paving the way for the Meso-gamma scale Z-coordinate model version New parameterization schemes forefront verification and case studies Perspective Issues are: Variational Methods for Estimating Local Parameters 03/01/2019
