Objectives
The objective of this workpackage is to generalize and up-scale the
ecosystem level observations in a more sophisticated modelling
framework that integrates local and spatial data with data- and
process-oriented models for improving across-scale CO2 balance
estimates over sub-Saharan African regions. Carbon balance estimates
and their seasonal and inter-annual variability are to be described
at local, regional and continental scales.
