Eddy covariance VOC emission and deposition fluxes above grassland using PTR-TOF
VOC grassland PTR-TOF
2011/2/24
Eddy covariance (EC) is the preferable technique for flux measurements since it is the only direct flux determination method. It requires a continuum of high time resolution measurements (e.g. 5–20 Hz...
