M. Young, etc. - beam is modulated to distinguish it from the background using a chopper wheel • A sonic anemometer measures the speed of sound in air using a short burst of ultrasound transmitted via a transducer. Another transducer then picks up the reflections of the sound. The delay between the transmitted burst time and the received time can be converted to the speed of sound if the distance between transducers is known. Such perceived speed of sound is actually the speed of sound in static air plus or minus the speed of the wind.

Ment connections after the instrument is installed and before data collection. The simplest leak test can be done by breathing around the instrument connections and away from the intake, and making sure that the CO2 signal does not increase.
