1. CNRM activities during CarboEurope Regional Experiment Strategy - forecasting support - wind profiler - Ceilometer - Radiosonde soundings - Surface flux station - drifting balloons - Piper Aztec Flights

2. Forecasting support Weather forecasts from the operational service of MF - summary of the situation of the day delivered on the website - forecaster present at the morning briefing (& evening if IOP) - Aladin outputs at D+1, D+2, D+3 Aladin outputs to force the STILT model (10 km, 72H) trajectories and back-trajectories from Aladin Available MesoNH outputs : - horizontal wind (at 500m and 10m) - mixing heights of BL - vertical profiles in BISCAROSSE, CS, MARMANDE (, TKE, wind) - vertical cross-section of mixing ratio for cloud/vapor Configuration : 2 nested models (240x240km at 8km and 60x60km at 2km) Beginning of the simulation with ALADIN forecast (10km) at D+ 27hTU End of the simulation : D+42h TU (8 km and 2km)

3. Wind profiler Location : La Cape Sud (agricultural buildings) Continuous dataset from 05/18 to 05/25 (14 UTC) and 06/02 to 06/23 Low mode configuration : profiles of wind speed and direction between 0- 2500m

4. Wind profiler RS at La Cape Sud : 11UTC Wind direction (°) Wind speed (m/s) 0° 180° 360° 0m/s 5m/s 10m/s direction speed IOP5 : Wednesday 15 June 2005

5. Ceilometer Useful to follow the Atmospheric Boundary Layer development <1500m in conditions of high specific humidity Deduced from sharp transitions in the profile of backscattered signal, related to the difference in aerosol and /or water vapor concentrations between the BL height and the overlying free troposphere Example of June 19 : maritime entrances in the morning RS La Cape Sud 17 UTC 1000m 2000m 3000m zizi

6. Radiosonde soundings Performed during IOP : 5, 8, 11, 14, 17, 23UTC In La Cape Sud : 96 with 5 to 6 per IOP day In Toulouse : 16 at 11 UTC Well-mixed and well developed ABL / strong nocturnal inversion ( 10K/200m) -max : 2000m on 05/27 & 2300m on 06/18 Saturday 18 June 5 UTC and 14 UTC La Cape Sud

8. Surface fluxes station - Le Fauga: fallow measurements : meteorological parameters, profiles of soil water content and soil temperature, - Soil density, LAI, CO 2 flux and energy balance - radiometer IR Profiles of soil temperatures between 06/13 and 06/21 at : - 1m - 5m - 20m - 50m - 90m

9. Surface fluxes station - Saint Sardos : maize field - measurements at 2m: meteorological parameters, profiles of soil water content and soil temperature, -Soil density, LAI, CO2 flux and energy balance W/m² Saint Sardos – 27 May 2005 0H00- 23H59 UTC Le Hs G Rn

10. Surface fluxes station : EC and REA systems La Cape Sud : beans field Eddy Correlation system at 2m Continuous measurements from 05/15 to 06/23 Meteo parameters, soil water content and temperature, LAI and biomass CO2, sensible and latent heat fluxes, momentum + Ozone fluxes (INRA)

11. Surface fluxes station La Cape Sud : beans field Relaxed Eddy Accumulation system at 2m Continuous measurements from 05/15 to 06/23 CO 2, NO x and latent heat fluxes for CO 2 : Li6262 for NO x : TEI 42 CTL In addition : NO soil emissions (performed by Laboratoire d’Aérologie) Saturday 06/11
