Description
Abstract
ABSTRACT
Monitoring the vegetation activity over long time-scales is necessary to discern ecosystem
responses to climate variability. Spatial and temporally consistent estimates of the
biophysical variables such as fractional vegetation cover (FVC) and leaf area index (LAI)
have been obtained in the context of DULCINEA Project. We used long-term monthly climate
statistics to build simple climatic indices (SPI, moisture index) at different time scales. From
these indices, we estimated that the climatic disturbances affected both the growing season
and the total amount of vegetation. This implies that the anomaly of vegetation cover is a
good indicator of moisture condition and can be an important data source when used for
detecting and monitoring drought in the Iberian Peninsula. The impact of climate variability
on the vegetation dynamics has shown not to be the same for every region. We concluded
that the relationships between vegetation anomaly and moisture availability are significant for
the arid and semiarid areas.
