Implications of jet stream and monsoon flow patterns on regional atmospheric inversions of CO2 fluxes over North America

Research output: Contribution to conferencePaper

Abstract

he role of the continental vegetation in the global carbon cycle remains greatly under-constrained due to complex biogeochemical processes responsible for the large variations observed in both space and time. While surface networks and satellite missions measuring atmospheric concentrations of CO2 offer an unprecedented amount of information relative to regional ecosystems, recent aircraft campaigns highlighted the impact of large-scale circulation by measuring spatial gradients through synoptic weather systems. Exploring further this problem in the context of regional-scale inversions, we investigate here how climatic patterns drive synoptic systems across North America, directly influencing the variability in observed CO2 mixing ratios and consequently our ability to estimate the influence of north American surface fluxes compared to large-scale air flows. Uncertainty estimates are derived from an ensemble of simulations using a mesoscale atmospheric modeling system. We focus on the
