6 HAIC/ HighIWC (2014 Darwin) Collaboration : international with more than 40 partners aircraft manufacturers, operators, research ) Fabien Deziter (Airbus) Mission: To sample zones of high concentration of liquid and solid water to improve new tools of forecasts of these types of zones The Means : F20 equipped with a microphysics radar and in situ probes Purpose: Reduce engine ploblems with planes during crossings of critical zones by improving the models of forecasts of these types of zones

7 BLLAST 2011 (France Lannemezan) Collaboration : CNRM, LA, OMP, U Paul Sabatier Marie Lothon (LA) Mission: to sample along tracks within 40 km of an instrumented site (the tray of Lannemezan) in parallel with drones and ULM Means : The PIPER aztec equipped for dynamics measurements : an Inertial system and fast humidity measurements. Purpose : Study of turbulent processes during the transition of the convective boundary layer at the end of the afternoon

8 Plan of the vertical explorations of aircraft. UAV = Unmaned Aerial Vehicle Zi = summit of the atmospheric boundary layer Ground tracks of working tracks (vertical plans) of the Piper

9 ITAAC / TC2 (2010 to 2014 France) Collaboration CNRS, DGAC, Dassault, CERFACS, ONERA Daniel Cariolle (CERFACS) Mission: To sample along the contrails from airliners to characterize the micrpphysics and chemistry of the particles in these contrails. Means: F20 equipped with chemistry and in situ microphysics probes Purpose: Modelling of the dynamics, physio chemical and radiative processes during various phases of formation of contrails and the validation of these simulations with airborne measurements To allow planes to avoid these zones by validating the digital simulations of trail

10 FENNEC (2011 Western Africa) Collaboration : LOA, LISA, CNRM, DT/INSU, LATMOS Cyrille Flamant (LATMOS/IPSL) Mission :To determine the 3 D structure of the troposphere and its regional variability ; to document the 3 D structure of the desert aerosols plume Means : F20 equipped with LIDAR aérosols, visible cameras, dropsondes (vertical soundings P,T,Hu) Purpose: to improve the understandig of the Saharan aerosol cycle, to identify the errors related to the lifting and transport of aerosols in large scale models, validation of aérosol products stemming from satellite observations.

14 GLAM (ChArMex SOP2 2 b) 2014 Méditerranean Sea Collaboration Univ. d Orléans, LPC2E, Univ.Paul Sabatier, L.A., IPSL,Univ. de Versailles, CEA, Univ. de Jérusalem,MF Philippe Ricaud (MF) Mission : Sample the East/west gradient of the occidental Mediterranean Basin and the seasonal variability of O 3, CO, CH 4, N 2 O et CO 2 (+ temperature et H 2 O) Means: F20 equipped with chemistry measurements and in site aerosols probes Purpose: To assess the differences between various models of E/W gradient of pollutants To assess the quality of models to improve the forecasting of chemical impact on the Mediterranean sea

15 Flight plan for GLAM experiment

16 HYMEX Mediterranean sea Collaboration CEMAGREF, CNES, CNRS INSU, INRA, Météo France Véronique Ducrocq (CNRM) Missions: To sample intensive rain episodes in front of and inside these systems To sample the dynamic of the air sea exchange during mediterranean cyclones Means: ATR and F20 equipped with Lidar,Radar, aerosols and microphysics probes, dropsonde Purpose: To improve the understanding of the modeling of the water cycle in the Mediterranean sea (forecast and evolution of the intensive events associated with the water cycle)

17 And soon. T NAWDEX (THORPEX North Atlantic Waveguide and Downstream Impact Experiment) during 2016 Gwendal Rivière Mission : sample upwelling zones of the warm conveyor belts (liquid and ice contents) and of the «bent back warm front / sting jets» Means : F20 equipped with RALI, dropsondes and microphysics probes Purpose : A better understanding of diabatic processes implied in the generation of atmospheric perturbations at mean latitudes in order to better understand the source of forecast errors.
