Phenology in the Alps

Since 2011, I started developping a network of high elevation grassland sites with continuous measurements of soil microclimate (volumetric water content, temperature) and phenology with ground measurements of Normalized Difference Vegetation Index (NDVI).

The network is maintained with the support of the Station Alpine J. Fourier, the Zone Atelier Alpes and the Centre de Recherche sur les Ecosystèmes d'Altitude.

A comparison with regional-scale phenology using relotely sensed data (MODIS) is also undertaken in collaboration with the national and regional parks involved in the Zone Atelier Alpes

NEW ! : See 13 years of greening anomalies* for the :
Parc National des Ecrins
Parc National de la Vanoise
Parc Naturel Régional du Vercors
Parc Naturel Régional du Massif des Bauges

* Anomaly for a given date of the year is estimated with the standard score (or z-score). In the presented maps, blue means a negative z-score (the greening for that year is lower than the average over 2000-2013); green means the reverse.
