Abstract:

A complete report of the general requirements for micrometeorological equipment used in CWS field work with respect to accuracy requirements for wind-speed measurements and accuracy requirements for temperature gradient measure is presented. The equipment for measurement of wind velocity is discussed and the following topics reviewed anemometer characteristics, operation of the relay-type frequency meter, devices used for recording wind direction, the vacuum-tube frequency meter, and direct-reading approximate R-value recording device. Investigations were conducted in the field of portable photo-electric galvanometer and measurement of temperature gradient and air and soil temperature. The details of the construction of the micrometeorological equipment are presented in detail.
