Winter carbon dioxide (CO₂) respiration from soils is a significant and understudied component of the global carbon (C) cycle. In this study, we were able to show with a field campaign and a model how windy (advective) conditions can affect the usually slow (diffusive) transport of CO₂ from soils and out of snowpacks. This research is important to help with understanding winter CO₂ dynamics, especially for continued accurate accounting of the annual global C cycle.
