LEANDRE 2 exploitation: Strategy
Utilisation systématique des données de vapeur d'eau issues des lidars
"vapeur d'eau" (le lidar aéroporté LEANDRE 2 et les lidars Raman de
Minorque et de Candillargues) pour confronter les modèles de climat
régionaux à l’IPSL
Deux aspects sont envisagés:
Une étude de la prévisibilité de la variabilité de la vapeur d'eau sur le bassin
Ouest Méditerranée qui utiliserai les données lidars et les prévis WRF faites à
J+1, J+2 et J+3,
Une étude sur l'impact du couplage océan-atmosphère sur la quantité et la
variabilité de vapeur d'eau au-dessus de la mer Méditerranée, qui utiliserait les
données lidars et les simuls CORDEX en mode couplé et non couplé (océanatmosphère).
LEANDRE 2 exploitation: Strategy
Projet ANR - MUSIC
Porté par le CNRM – V. Ducrocq
Partenaire LATMOS (LATMOS, LSCE, LMD, Univ Basilicata)
The overarching objective of Task 1c is to ensure that the water vapor measurements
acquired during the SOP 1 of HYMEX are consistent, self-coherent and can be used
unambiguously in order to analyse the variability of the water vapor field over the
Western Mediterranean Basin.
This will be achieved through careful and thoughtful inter-comparison for the IOPs
between all water vapor measuring devices involved (LIDARs, RS, GPS, pressurized BL
balloons, in situ aircraft).
Two objectives:
1. Produce error and bias estimates for the water vapor profiles in the lower and midtroposphere issued from the different water vapor lidars based on an intensive intercomparison effort (lidar-to-lidar, lidar-to-sounding, lidar-to-balloon),
2. Validation of water vapor fields from
• AROME WMED forecasts &reanalyses
• Meso-NH simulations performed with 2.5-km and 500-m horizontal mesh size
Contribute to study of the multiscale interaction between ambient flow and deep
convection that governed the HPEs observed during the SOP1,

ATR Flights (2 over the Gulf of Lion)
a) Montpellier – Bastia & Bastia-Montpellier
b) Survey of moist inflow towards NEI over the Gulf of Genoa, the Po Valley and

low level southeasterly flow advecting humid air.
The German Do128 performed two flights in the morning and afternoon at
different heights along the Northern and Eastern coast of Corsica, to document
fluxes over the Ligurian Sea (low level flights & soundings)
