- Observation Diurnal carbon dioxide variation reached 100 vpm in the canopy and diminished with height.
- Mechanism Daytime photosynthetic intake and nighttime plant and soil respiration drove the diurnal carbon dioxide variation.
- Association Irregular carbon dioxide variations had 3 to 5 day periods and appeared linked to synoptic weather.
- Observation Mean daily carbon dioxide decreased 28 vpm from June to September.
