Introduction to Atmospheric Measurementsy, low heat capacity, and transparency to a large part of the electromagnetic spectrum) and the fact that the air is almost always in (often turbulent) motion. The vertical and horizontal distributions of meteorological elements and the spatial and temporal scales of processes strongly influence the

Temperature Sensorsmeters, and the most commonly used instruments: resistance thermometers. Radiation shields and ventilation are important for minimizing erroneous results. Fine-wire thermometers and sonic temperature measurement are important techniques for turbulence measurements. In addition to providing technical

Current sensor technology is mostly based on the psychrometric method, dewpoint measurements, and optical measurements, as well as capacitive sensors. Of special interest are the psychrometric theory and the theory of op

Wind Sensorsto measure the wind vector. Wind direction measurements are also performed using wind vanes. Sonic anemometers are the devices most commonly used for turbulence measurements. Hot-wire anemometers are employed for special measurements, and Pitot tubes are utilized for aircraft-based measurements. It
