1. COPS - FRANCE Proposal submitted to ANR White call – March 2006

2. PARTICIPANTS CNRM (Météo-France, Toulouse) LMD and SA (CNRS/IPSL, Paris) LaMP (CNRS, Clermont-Ferrand) LA (CNRS, Toulouse)

3. ACTIVITIES Instrumentation Modelling Data assimilation

4. 1 - Implementation of a supersite in the Vosges area

5. Required instrumentation for the supersite (C. Flamant) RS station UHF wind profiler + sodar Surface flux station (and possibly scintillometer) TReSS (Transportable Remote Sensing Station) Raman lidar X and K band radars (and possibly disdrometers and rain gauges)

6. Open questions … Supersite location ? Optimum distribution of the instruments between the different sites

7. 2- Deployment of a GPS network (J. Van Baelen) 2 existing stations in Alsace region and potentially 2 to 5 more in the Vosges region by 2007 16 or more GPS temporary stations from INSU pool of instrumentation To be installed in northeastern France

8. Open questions … Homogeneous distribution over the COPS area Denser network around the supersite Need for specific GPS coordination Real time transmission ?

9. 3 – Operations upstream at the SIRTA (M. Haeffelin) Located 20 km south of Paris Radars, lidars, and radiometers Radar data from Montancy sent in real time 4 – Routine observations from Météo-France

10. Modelling Clark’s model + DESCAM (very detailed microphysics – bin type model from CCN/ICN to liquid/solid precipitation) Méso-NH model (two-moment microphysics) AROME (systematic forecasts within MAP-D-PHASE)

11. Data assimilation 3D-Var AROME data assimilation system In real time, all conventional available meso-scale observations After the experiment, GPS zenith delays and radar data

12. Future plans... Airborne operation (Falcon + LEANDRE II dial water vapor lidar + dropsondes) ~30 hours – 1 month - ~ 100 DS Proposal(s) to be submitted to LEFE/IDAO and/or CNES)

13. French Operational Radars Nancy : Doppler, Single polar. 3 rotations / 5’ Montancy: Doppler / Double plolar. 6/8 rotations / 5’ 12 elevations / 15 ‘
