We quantify atmosphere-biosphere carbon exchange at
the continental scale across North America
during the summers of 2003 and 2004. The 2003 campaign features continental
transects across the northern portion of North America with significant
influence from biomass burning, while the 2004 study focuses on the greater New
England and Quebec
region. We use a Lagrangian, adjoint atmospheric model [Gerbig et al. 2003a,b; Lin et
al. 2003] coupled to a biosphere model derived from the Vegetation
Photosynthesis Model [Xiao et al.,
2004]. Our analysis of the 2004 airborne data demonstrates the progression of
increasing carbon uptake through the boreal zone during the seasonal transition
from early spring to late summer. Data from the coast-to-coast transects of the
2003 campaign allow us to quantify large scale carbon exchange across the
continent.
