A novel experimental study of aeolian snow transport in Adelie Land (Antarctica)
peer reviewed None of the previous aeolian snow transport campaigns in Antarctica meet the requirements in terms of tempo- ral resolution, long-term series and qualified instruments for evaluations of meteorological and climate models including parameterization for aeolian snow transport.

peer reviewed None of the previous aeolian snow transport campaigns in Antarctica meet the requirements in terms of tempo- ral resolution, long-term series and qualified instruments for evaluations of meteorological and climate models including parameterization for aeolian snow transport. Consequently, determining the quantity of snow transported remains a challenge. A field campaign was therefore launched in January 2009, in Adélie Land, Antarctica, to acquire new model-evaluation-oriented observations within the European ICE2SEA project, with the logistical support of the French polar Institute (IPEV). The available aeolian snow transport sensors are reviewed and the sensor that best suited our specific needs was chosen: FlowCaptTM acoustic sensors. Three au- tomatic weather stations were deployed with FlowCaptsTM close to the coast. The stations' locations are distinct, ranging from 1 to 100 km inland, one of them with a 7-m mast with six levels of anemometers and thermohygrometers.
