Method:

A pair of 3D sonic anemometers will be used to measure a vertical gradient of turbulence and vertical wind fluctuations.  These will be combined with trace gas measurements to estimate vertical fluxes.

Alkyl halides will be measured simultaneously at several vertical by concentrating air samples on solid adsorbent tubes that will be thermally desorbed and analyzed using Gas Chromatography with Mass Spectrometry.
