Col de Porte snow and meteorology field site
The Col de Porte pilot site is located near Grenoble, in the Chartreuse massif (elevation : 1325m, latitude : 45°30’N, longitude : 5°77’ E). At this mountain site, on the flat measurements field (pictures), meteorological and snow parameters are recorded hourly since 1961.
These parameters are :
Air temperature and humidity
Short- and long-wave radiations
Wind speed and precipitation
Snow depth, snow water equivalent
Settlements and snow temperatures of the different layers of the snowpack
Weekly snowpack profiles are also carried out, including major stratigraphic properties of snow (temperature, density, liquid water content, snow type).
The Col de Porte site has been widely used to build and evaluate snowpack models such as Crocus, using its unique high-resolution snow and meteorological measurements. In addition, such measurements are useful to monitor the effects of climate change on the Alpine snow cover.
The site is also extremely useful for testing dedicated instrumentation, and carrying out innovative research in the field or in the cold room attached to the laboratory.
The experimental site col de Porte is linked to related observation networks such as the national monitoring observatory GLACIOCLIM and the SOERE CRYOBS-CLIM (Systèmes d’Observation et d’Expérimentation, sur le long terme, pour la Recherche en Environnement de la CRYosphère, un Observatoire du CLIMat) of OSUG (Observatoire des Sciences de l’Univers de Grenoble).

The site is operated since 1959.
Daily snow and met data are available graphically. For more information, please contact yves.lejeune.at.meteo.fr
Hourly quality controlled snow and met data are available for research purpose. In the past, they have been used for hydrologycal or snow model development and evaluation.
These pages allow you to view sample images of snow crystals and grains at different stages of their metamorphisms. The photos were taken in the cold laboratory of the Col de Porte
