Short summary
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.
