Large impact of coarse-resolution atmospheric transport model error on land-ocean and tropic-extratropic partitioning and seasonal cycle in CO2 inversion
Abstract:We show that forward simulations of global CO2 using an atmospheric
transport model (ATM) at 0.5°×0.625° and 4°×5° resolutions differ
significantly in vertical and meridional distribution. Comparing two
observing simulation system experiments at 4°×5° resolution that
assimilate pseudo observations sampled from the two forward simulations,
we isolated the impact of coarse-resolution ATM error on regional flux
estimates that a significant amount of annual carbon uptake from the
ocean and tropics is improperly re… Show more
