Detecting fossil fuel emissions patterns from subcontinental regions using North American in situ CO₂ measurements.

ABSTRACT: The ability to monitor fossil fuel carbon dioxide (FFCO₂) emissions from subcontinental regions using atmospheric CO₂ observations remains an important but unrealized goal. Here we explore a necessary but not sufficient component of this goal, namely, the basic question of the detectability of FFCO₂ emissions from subcontinental regions. Detectability is evaluated by examining the degree to which FFCO₂ emissions patterns from specific regions are needed to explain the variability observed in high-frequency atmospheric CO₂ observations. Analyses using a CO₂ monitoring network of 35 continuous measurement towers over North America show that FFCO₂ emissions are difficult to detect during nonwinter months. We find tha
