- Observation Diurnal carbon dioxide variation reached 100 vpm in the canopy and diminished with height.
- Association Irregular carbon dioxide variations had 3 to 5 day periods and appeared linked to synoptic weather.
- Observation Carbon dioxide fell with longer trajectories over land, differing by up to 7 vpm in daily minima.
- Observation Mean daily carbon dioxide decreased 28 vpm from June to September.
