The response of a Kaijo Denki DAT 300 ultrasonic anemometer-thermomete
r is analyzed with respect to temperature and vertical velocity. The e
ffects of the emitting-receiving cycle of the transducer array on w, T
, and Co(wT) 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.
