Some Instruments Used by Division 10, NDRC at Dugway Proving Ground for Continuous Recording of Micrometeorological Conditions
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.
