Interaction between the atmosphere and a coniferous forest is examined based on a turbulence experiment. The daytime co-spectra of heat flux, water vapor flux and CO2 flux are similar in shape. They have steeper however, when compared to co-spectra obtained over short plants, which means that turbulent transport occurs over a more limited range of eddies over a forest. The correlation coefficient between the vertical wind component and temperature or specific humidity is approximately 0.5 for unstable conditions, though that for CO2 is less.
