Comments on Measuring Turbulent Exchange Within and Above Forest Canopy

Abstract

Actual problems of measuring the turbulent exchange in and above forests (e.g., site requirements of micrormeteorological observations, aerodynamic characteristics of forests, observations of the crown-produced mixing layer, flux-profile relationships above forests, and some experimental difficulties) are discussed. The present state of knowledge regarding the micrometerology of forests is poor, and there are good opportunities for experimental and theoretical research. A wider participation of universities and research institutes (in forest meteorological research) and their international coordination is needed.
