BVOC ecosystem flux measurements at a high latitude wetland site
BVOC ecosystem flux measurements high latitude wetland site
2010/2/21
In this study, we present summertime concentrations and fluxes of biogenic volatile organic compounds (BVOCs) measured at a sub-arctic wetland in northern Sweden using a disjunct eddy-covariance (DEC)...
Constraining the concentration of the hydroxyl radical in a stratocumulus-topped marine boundary layer from sea-to-air eddy covariance flux measurements of dimethylsulfide
hydroxyl radical stratocumulus-topped marine boundary layer sea-to-air eddy covariance flux measurements
2009/12/31
The hydroxyl radical (OH) is an important oxidant in the troposphere due to its high reactivity and relative abundance. Measuring the concentration of OH in situ, however, is technically challenging. ...

Eddy covariance flux measurements pollutant gases urban Mexico City
2009/10/9
Eddy covariance (EC) flux measurements of the atmosphere/surface exchange of gases over an urban area are a direct way to improve and evaluate emissions inventories, and, in turn, to better understand...
Mixing ratios and eddy covariance flux measurements of volatile organic compounds from an urban canopy
Mixing ratios eddy covariance flux measurements volatile organic urban canopy
2009/3/31
Mixing ratios and fluxes of six selected volatile organic compounds (VOCs) were measured above the city of Manchester (UK) during the summer of 2006. A proton transfer reaction-mass spectrometer was u...

Within the framework of the AFO 2000 project ECHO, two PTR-MS instruments were operated in combination with sonic anemometers to determine biogenic VOC fluxes from a mixed deciduous forest site in Nor...
Technical note: Water vapour concentration and flux measurements with PTR-MS
Water vapour concentration flux measurements PTR-MS
