Carbon dioxide flux density

Figure 8. The high frequency nature of the vertical velocity (W), water vapor (q ), and CO2 densities (C ) at 2 meters above a soybean canopy during a 3 minute period. The illustration also shows instantaneous water vapor (W q ) and carbon dioxide (W C ) fluxes and the mean quantities for the 15 minute period from which these traces were taken.
