Zusammenfassung |
This paper investigates the relationship between the heterogeneity of
the terrestrial carbon cycle and the optimal design of observing
networks to constrain it. We combine the methods of quantitative
network design and carbon-cycle data assimilation to a hierarchy of
increasingly heterogeneous descriptions of the European terrestrial
biosphere as indicated by increasing diversity of plant functional
types. We employ three types of observations, flask measurements of
CO2 concentrations, continuous measurements of CO2
and pointwise measurements of CO2 flux. We show that flux
measurements are extremely efficient for relatively homogeneous
situations but not robust against increasing or unknown
complexity. Here a hybrid approach is necessary, and we recommend its
use in the development of integrated carbon observing systems. |
