Canopy Transport Processes: Commentary

  • G. W. Thurtell

Summary

The theory of canopy transport processes has progressed rapidly during the last few years and the inadequacy of K-theory, which is based on simple linear diffusion concepts, is now clear. Unfortunately the new concepts are more complex and remain difficult to exploit for the description of diffusion in field situations.

The development of readily usable canopy transport models is dependent on the availability of high quality data sets. The current increase in the number of canopy diffusion experiments is appropriate and continued progress is anticipated.
