Relevance of a Tuning-Fork Effect for Temperature Measurements with the Gill Solent HS Ultrasonic Anemometer-Thermometer

摘要

The performance of a new type of sonic anemometer-thermometer (called a sonic), the Solent-Research HS, manufactured by Gill Instruments, Lymington, United Kingdom, was investigated. Measurements of the three wind-velocity components u, v, w, and temperature T were taken in the laboratory under quiet conditions and in the field at wind speeds of about 10 m s~-1. The power spectra of u, v, w, and T measured in the laboratory follow a -5/3 power law at moderate frequencies.
