Eddy covariance virtual disjunct

EC = Eddy covariance DEC = disjunct eddy covariance vDEC = virtual disjunct eddy covariance REA = relaxed eddy accumulation EM = enclosure method CBL = conveaive boundary layer budgeting MEG = mixed layer gradient MLV = mixed layer variance. 

Karl, T.G., Spirig, C, Rinne, J., Stroud, C., Prevost, R, Greenberg, J, Fall, R., Guenther, A. (2002) Virtual disjunct eddy covariance measurements of organic compound fluxes from a subalpine forest using proton transfer reaction mass spectrometry. Atmospheric Chemistry and Physics, 2,279-291. 

Karl et al. tested a virtual disjunct eddy covariance device with field measurements of biogenic VOC fluxes at a subalpine forest site in the Rocky Mountains of the United States [84], where a short grazing season is only possible owing to the altitude. Significant fluxes of MBO, methanol, acetone and acetaldehyde were observed.
