Csat3 sonic anemometer
WebSonic anemometers simultaneously measure the turbulent fluctuations of vertical wind ( w ') and sonic temperature (T '), and are commonly used to measure sensible heat flux (H). Our study examines 30-min heat fluxes measured with a Campbell Scientific CSAT3 sonic anemometer above a subalpine forest. Web462 HEPING LIU ET AL.
