Abstract
Technological developments from last decades oer unprecedented opportunities to
monitor the Earth system. International research projects like BACI are joint eorts to
provide free-of-charge, uni ed and high quality Earth Observations and the development
of tools to analyze them. The ability to detect and monitor anomalous behaviour in multivariate
environmental time series is crucial. These events are signals of changes in the
underlying dynamical system and their detection can be used as an early-warning system
for land ecosystems. In this study we present a methodology to detect these anomalies
in biosphere data by a combination of a multivariate autoregressive model together with
a distance measure. This work is framed within the EU-funded project BACI 'Detecting
changes in essential ecosystem and biodiversity properties - towards a Biosphere Atmosphere Change Index'.
