Carbon dioxide uptake by plants is a major component of the global carbon cycle that can be affected by climate change. This experiment quantifies the rate of landscape exchange of CO2 in the time between a high altitude balloon’s ascent and descent. It was hypothesized that measured seasonal trends would match a predicted trend of spring and fall release and summer uptake showing that the high altitude balloon method was a valid method. This was supported by the collected data where three flights showed landscape uptake, seven flights showed release and four showed no net exchange.
