Space–time LAI variability in Northern Puglia (Italy) from SPOT VGT data

Gabriella Balacco, Benedetto Figorito, Eufemia Tarantino, Andrea Gioia, Vito Iacobellis
2015 Environmental Monitoring & Assessment  
The vegetation space-time variability during 1999-2010 in the North of the Apulian region (Southern Italy) was analysed using SPOT VEGETATION (VGT) sensor data.  ...  The space-time distribution of LAI at the catchment scale was analysed over the examined period to detect the consistency of vegetation dynamics in the study area.  ...  However, extracting trends from time series can be challenging due to short-term (e.g. phenological) variations in the data or overall low signal-tonoise ratios (Verbesselt et al. 2010) .  ...
