as the link you included states, this is at 8km high in the atmosphere
isn't it impressive how atmospheric mixing gets that ground sourced CO2 up there ...
and, as the link states
"despite the high degree of mixing that occurs with carbon dioxide, the regional patterns of atmospheric sources and sinks are still apparent in mid-troposphere carbon dioxide concentrations. "This pattern of high carbon dioxide in the Northern Hemisphere (North America, Atlantic Ocean, and Central Asia) is consistent with model predictions,""
Hope you learned something Lucky, and have a good weekend
