Description du projet
Réseau lidar innovant pour la mesure de l’atmosphère
Les efforts visant à atténuer le changement climatique ont rendu d’autant plus important le fait de comprendre et de surveiller la physique atmosphérique (y compris la distribution des vents et des températures dans l’atmosphère). Il est indispensable d’améliorer les modèles climatiques et les prévisions météorologiques. Les données de mesures continues au-dessus d’une altitude de 5 km, seuil qui correspond à l’altitude maximale des lidars et radars éoliens compacts commerciaux, font toutefois défaut. Le projet EULIAA, financé par l’UE, mettra au point un réseau de lidars capable de mesurer de manière autonome le vent et la température atmosphériques à une altitude comprise entre 5 et 50 km et ce, 24 heures sur 24, 7 jours sur 7, sur une longue période (plus d’un an sans maintenance) et couvrant une grande zone d’observation (jusqu'à 10 000 km2). Les nouvelles unités lidar sont bon marché, compactes, efficaces, facilement transportables et alimentées par des éoliennes ou des panneaux solaires.
Objectif
The importance of understanding and monitoring atmospheric physics has increased drastically in recent years due to the anthropogenic impact on climate. One crucial research field is the understanding of wind and temperature distributions in the atmosphere to enhance climate models and improve weather forecasts.
There is currently a major data gap for continuous measurements above 5 km, which is the maximum height of commercial compact wind radars and lidars.
The goal of EULIAA is the development of a lidar array measuring autonomously the atmospheric wind and temperature from 5 km up to 50 km on a 24/7-basis over a long period of time (> 1 year without maintenance) and covering a large observation area (up to 10’000 km2). EULIAA’s lidar units are low-priced, compact, efficient, easily transportable, and autonomous thanks to low power requirements (by wind turbines or solar panels).
EULIAA will yield novel data sets in near real-time for implementation into European databases Copernicus and GEOSS, that will fill current data-gaps and help to monitor the effects of climate change and to evaluate climate protection measures.
The baseline technology was demonstrated in the first field campaign with a lidar system that operates in the IR and is currently being transferred to a European industrial partner.
Once the enhanced capability developed within EULIAA has been demonstrated and validated in difficult-to-reach regions (polar, equatorial, and mountain), with a high TRL (6–8), a business plan and roadmap for an European array will be produced, involving relevant industrial, standardisation, and end-user actors.
The EULIAA project (48 months and 3M€ grant requested) gathers 7 partners from 5 countries with experts in lidar and its subsystems, atmospheric observatories, and atmospheric data provider. It contains all the necessary disciplines to ensure the technological development, data transfer, and sustainable exploitation.
