A long-term (over 20 years) meteorological and blowing snow observations dataset from the high-elevation alpine site Col du Lac Blanc, France, 2720 m a.s.l.

The present dataset encompasses meteorological, snow and blowing snow data from the winter 2000-2001 on, for the high altitude Col du Lac Blanc site (2 720 m a.s.l.) as part of the snow and glacier observatory GLACIOCLIM within the OZCAR critical zone observatory in France. These data have been used in the past to develop and evaluate physical parameterizations and numerical models of blowing and drifting snow in alpine terrain. They currently also support the evaluation of meteorological(NWP) models, climate models and remote-sensing products and algorithms in alpine, snow covered terrain, and more data serving that purpose can be downloaded from the doi attached to the datapaper Guyomar’ch et al 2019. In collaboration with other institutes they also help to understand the spatial variability and functionning of mountain ecosystems.A further view is their use to document the effects of climate change at high altitudes in the French Alps.
