	<abstract content_type="html">Climate change induces long-term changes in soil-moisture. These changes can
have important effects on the terrestrial biosphere, which can feedback into
the climate system. In the past years there have been many attempts to
produce and improve global soil-moisture datasets, however, comparing and
validating these various datasets is not an easy task. Here, interannual
variations in indices of soil moisture are compared to interannual changes
in vegetation, as captured by NDVI. By comparing the correlations of the
different indices with NDVI we evaluated which soil moisture index provides
the most reliable soil moisture representation. We showed that NDVI can be
used as an external validation dataset to soil moisture indices, in areas
that are classified as warm temperate climate with hot or warm dry summers.
Using the best performing index, NSM (Normalizes Soil Moisture), and the ICA
(Independent Component Analysis) technique, we analyzed the response of
vegetation to temperature and soil-moisture stresses over Europe.</abstract>
