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...

As part of the OP3 field study of rainforest atmospheric chemistry, above-canopy fluxes of isoprene, monoterpenes and oxygenated volatile organic compounds were made by virtual disjunct eddy covarianc...
Regional-scale geostatistical inverse modeling of North American CO2 fluxes: a synthetic data study
Regional-scale geostatistical North American CO2 fluxes a synthetic data study
2010/8/16
A series of synthetic data experiments is performed to investigate the ability of a regional atmospheric inversion to estimate grid-scale CO2 fluxes during the growing season over North America. The i...
During two field campaigns (OP3 and ACES), which ran in Borneo in 2008, we measured large emissions of estragole (methyl chavicol; IUPAC systematic name 1-allyl-4-methoxybenzene; CAS number 140-67-0) ...
