Abstract
The response of a Kaijo Denki DAT 300 ultrasonic anemometer-thermometer is analyzed with respect to temperature and vertical velocity. The effects of the emitting-receiving cycle of the transducer array on w, T, and CowT spectra are considered. The resulting relations are used to interpret temperature spectra obtained during the HEXMAX (Humidity Exchange over the Sea, Main Experiment) measuring campaign.
