Remote Sensing Input for Regional to Global CO2 Flux Modelling
The current and future strength of the terrestrial carbon
sink has a crucial influence on the expected climate
warming on Earth. Usually, Earth Observation (EO) by
its very nature focusses on diagnosing the current state
of the planet. However, it is possible to use EO products
in data assimilation systems to improve not only the diagnostics
of the current state, but also the accuracy of future
predictions.
This contribution reports from an on-going ESA funded
study in which the MERIS FAPAR product is assimilated
into a terrestrial biosphere model within the global Carbon
Cycle Data Assimilation System (CCDAS). Results
are presented from a range of selected sites spanning the
major biomes of the globe, and show how the inclusion
of MERIS products results in improved accuracy of the
regional carbon flux estimates. They also show the uncertainty
in the predicted carbon sink of those regions for
selected climate scenarios until 2039.
