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. 

Rinne et al. used PTR-MS with a disjunct eddy covariance method to measure the fluxes of methanol, acetaldehyde and monoterpenes above a Scots pine (Pirns sylvestris) forest in Finland [90]. Chemical modeling showed that there was little loss owing to reaction and that the VOC fluxes followed the traditional exponential temperature-dependent emission... 

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. 

The perennial plant alfalfa is an important forage crop that is cultivated in many countries. Warneke et al. measured the fluxes of selecfed oxygenated VOCs coming from an alfalfa field before, during and after harvesting, using disjunct eddy covariance methods combined...
