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...
Impact of biomass burning on ocean water quality in Southeast Asia through atmospheric deposition: field observations
biomass burning ocean water quality Southeast Asia atmospheric deposition field observations
2010/12/20
Atmospheric nutrients have recently gained considerable attention as a significant additional source of new nitrogen (N) and phosphorus (P) loading to the ocean. The effect of atmospheric macro nutrie...
Atmospheric deposition of mercury and major ions to the Pensacola (Florida) watershed: spatial, seasonal, and inter-annual variability
mercury major ions the Pensacola (Florida) watershed inter-annual variability
2010/8/13
Atmospheric deposition was measured at three sites in the Pensacola Bay watershed, Florida, between November 2004 and December 2007. Mercury deposition in the Pensacola Bay watershed was similar to th...

Simultaneous coastal measurements of ozone deposition fluxes and iodine-mediated particle emission fluxes with subsequent CCN formation
ozone deposition fluxes iodine-mediated particle emission fluxes subsequent CCN formation
2010/1/18
Here we present the first observations of simultaneous ozone deposition fluxes and ultrafine particle emission fluxes over an extensive infra-littoral zone. Fluxes were measured by the eddy covariance...
Hydrogen soil deposition at an urban site in Finland
