First LiDAR measurement campaign underway at Penn-Avel
The scanning LiDAR, a wind measurement instrument recently acquired by the LHEEA (summer 2019, funding from the region, ERDF, PIA), was installed on the terrace of the seafront villa in Penn Avel park on the Croisic site on 28 October 2019.
on February 28, 2020
Its deployment meets the needs of two LHEEA research projects on the coastal atmosphere: MATRAC and WAKEFUL. The location is ideal because of the clear view from south east to south west, the prevailing wind sector in the area.
The LiDAR is configured to measure the wind above the sea at six heights constituting three virtual met masts at 1 km, 2 km and 3 km from the coast. Measurements are taken at 10 min intervals over a 45 ° wind sector. In addition to the specific project needs, this first deployment is the opportunity to acquire experience using this tool and to test new functionalities.
Objectives of the LIDAR campaign at Penn-Avel: Characterise offshore wind, at different distances from the coast, and assess the potential of LiDAR for measuring marine aerosols.
Financing: ANR ASTRID (2019 - 2021)
Partners: Mediterranean Institute of Oceanology (MIO, coordinator), LHEEA (Isabelle Calmet, DAUC and SEM-REV teams, in collaboration with TNO (Netherlands)), Interdisciplinary Centre for Nanosciences of Marseille (CINaM)
Project objectives:
The result of successful collaboration between the DAUC and SEM-REV teams.

MATRAC Project: Atmospheric Modelling for Electromagnetic Transmission Radiations in the Coastal Atmosphere
MATRAC aims to improve knowledge of dynamics and optical properties of the marine aerosol in the coastal area in order to:- better understand spatio-temporal variations of the particulate extinction coefficient.
- assess the impact of these variations on electro-optical radiation
- validate an extinction model operating on the basis of a small number of inputs

WAKEFUL Project: Wake unsteadiness measurements and analysis for FOWT using LiDARs
Project objectives:
- develop a measurement strategy by LiDAR from a floating platform,
- measure the unsteady wake of an offshore wind turbine,
- analyse existing wake models and propose improvements,
- measure the offshore wind resource.
Funding: WEAMEC (2019-2022)
Partners: LHEEA (coordinated by Boris Conan, DAUC, EMO & SEM-REV), the University of Stuttgart, IDEOL
