    Research output: Contribution to journalJournal articleResearchpeer-review


    For an ongoing elevated-source, urban-scale tracer experiment, an instrument system to measure the three-dimensional wind velocity and the turbulent sensible heat flux was developed. The wind velocity was measured with a combination of cup anemometer, propeller (vertical) and vane sensor. The temperature fluctuations were derived using a uniquely referenced thermocouple pair. The temperature sensor is described in detail. The wind sensors have already been described elsewhere
