The measurements

In this chapter the measuring system will be described first (). The profile method is introduced in section , together with the neccessary corrections. A method for calculating turbulent fluxes by means of the similarity theory will be presented. The direct flux measurements carried out at 82 m above the ground will be given in section . The monitoring system and the calibration will be described in detail. Data processing section is divided into subsections to deal with all the neccessary steps. In the last section () the Japanese system will be described. Their equipment will be described briefly, then the steps of calibration and data processing will be discussed.
