description:Abstract;"The Col du Lac Blanc observatory is located near l'Alpe d'Huez resort in the Grandes-Rousses massif and is dedicated to study interactions between the cryosphere and the atmosphere at high altitudes, with a focus on blowing and drifting snow studies. The site is managed by Météo-France (CNRM/CEN) and IRSTEA (Université Grenoble Alpes). It comprises four stations: Lac Blanc (CRYOBSCLIM.CLB.LacBlanc), Muzelle (CRYOBSCLIM.CLB.Muzelle), Dome (CRYOBSCLIM.CLB.Dome) and Col (CRYOBSCLIM.CLB.Col).
The pass orientation and the specific configuration of the surrounding summits make it closely resemble a natural wind tunnel. The north–south direction accounts for 90% of the wind directions. Aeolian snow transport is observed 10% of the time in winter and occurs with concurrent snowfall 37% of the time (Vionnet et al., 2013, Advances in Water Resources).
The experimental site and related instrumentation are described in details in Guyomarc’h et al. (2018). Available data acquired during winter seasons include wind speed and direction, drifting snow fluxes, snow height, air temperature. A database (CRYOBSCLIM.CLB.BSO) of hourly blowing snow occurrence achieving through an empirical method is also provided. Hourly meteorological outputs of the SAFRAN meteorological analysis system (Durand et al., 2013, Annals of Glaciology) are also available (CRYOBSCLIM.CLB.SAFRAN). In this way, humidity, downwelling and upwelling radiations from reanalysis are also included. Data have been used to evaluate and develop physical parameterizations of blowing and drifting snow in alpine terrain. Snowpack models and atmospheric models simulating wind -induced snow transport have also been evaluated at this site. Finally, Col du Lac Blanc is a target site to evaluate Numerical Weather Prediction (NWP) models in alpine terrain.
