Check out the main results of the action Pheno_Detect that was focused on the use of webcam images to track phenological development and on the elaboration of MODIS data

RES PDweb_combo

2000-2010 MODIS NDVI data have been processed (Busetto et al 2006, Global Change Biology) to estimate the main phenological events, such as start, end and duration of the growing season, of larch forests and alpine grasslands in Aosta Valley and France.

RES PDmodis_1

The plot above shows, as an example, the time series of the start of the growing season (SOS) of alpine grasslands in the last ten years in France (upper-left panel) and in Aosta Valley (lower-left panel); On the right the anomalies in SOS dates are plotted against the anomalies in April-May-June mean air temperatures: the slope of the regression line is very similar in France (upper-right) and Aosta Valley (lower-right) and indicates the sensitivity of grasslands SOS dates to variations in spring temperatures. An increase of 1°C in spring temperature results in an anticipation of SOS of 7/8 days.
