Turbulence Measurements from a T-Array of Meteorological Sensors.
Abstract
An array of meteorological instruments is described along with the fundamental characteristics of the instrumentation. Processing of data obtained with this array which forms a configuration of a T is discussed. Turbulence data computed from fast-response wind and temperature sensors placed at heights of 1.5, 4.0, and 16.0 meters above a heterogeneous semiarid terrain are presented. Data from the system were digitally recorded on magnetic tape compatible with digital computers at a rate of one scan per second even though the system is capable of scanning at one, two, or four scans per second. Data blocks of 15 minutes were utilized to obtain means and standard deviations of wind components and temperature, eddy correlations, vertical fluxes of heat and momentum and a stability index z/L. More than 150 hours of data collected during the months of January through April 1970 in blocks of data of time intervals of 2 to 7 hours are presented. (Author)
