Abstract :
[en] The Integrated Carbon Observation System is
a Pan-European distributed research infrastructure that has as its
main goal to monitor the greenhouse gas balance of Europe. The
ecosystem component of Integrated Carbon Observation System
consists of a multitude of stations where the net greenhouse gas
exchange is monitored continuously by eddy covariance measurements
while, in addition many other measurements are carried out
that are a key to an understanding of the greenhouse gas balance.
Amongst them are the continuous meteorological measurements
and a set of non-continuous measurements related to vegetation.
The latter include Green Area Index, aboveground biomass and
litter biomass. The standardized methodology that is used at the
Integrated Carbon Observation System ecosystem stations to
monitor these vegetation related variables differs between the
ecosystem types that are represented within the network, whereby
in this paper we focus on forests, grasslands, croplands and mires.
For each of the variables and ecosystems a spatial and temporal
sampling design was developed so that the variables can be
monitored in a consistent way within the ICOS network. The
standardisation of the methodology to collect Green Area Index,
above ground biomass and litter biomass and the methods to
evaluate the quality of the collected data ensures that all stations
within the ICOS ecosystem network produce data sets with small
and similar errors, which allows for inter-comparison comparisons
across the Integrated Carbon Observation System ecosystem
network.
