Summary: | A meteorological and blowing snow data set from the
high-elevation experimental site of Col du Lac Blanc (2720 m a.s.l.,
Grandes Rousses mountain range, French Alps) is presented and detailed in
this paper. Emphasis is placed on data relevant to the observations and
modelling of wind-induced snow transport in alpine terrain. This process
strongly influences the spatial distribution of snow cover in mountainous
terrain with consequences for snowpack, hydrological and avalanche hazard
forecasting. In situ data consist of wind (speed and direction), snow depth
and air temperature measurements (recorded at four automatic weather
stations), a database of blowing snow occurrence and measurements of blowing
snow fluxes obtained from a vertical profile of snow particle counters
(2010–2016). Observations span the period from 1 December to 31 March
for each winter season from 2000–2001 to 2015–2016. The time
resolution has varied from 15 min until 2014 to 10 min for the last years.
Atmospheric data from the meteorological reanalysis are also provided from
1 August 2000 to 1 August 2016. A digital elevation model (DEM) of the study
area (1.5 km2) at 1 m resolution is also provided in RGF 93 Lambert 93
coordinates. This data set has been used in the past to develop and evaluate
physical parameterizations and numerical models of blowing and drifting snow
in alpine terrain. Col du Lac Blanc is also a target site to evaluate meteorological and climate
models in alpine terrain. It belongs to the CRYOBS-CLIM observatory (the
CRYosphere, an OBServatory of the CLIMate), which is a part of the national
research infrastructure OZCAR (Critical Zone Observatories – Application and
Research) and have been a Global Cryospheric Watch Cryonet site since 2017.
The data are available from the repository of the OSUG data centre
