Total gaseous mercury (TGM) was measured onboard a passenger aircraft during monthly CARIBIC flights (Civil Aircraft for Regular Investigation of the Atmosphere Based on an Instrumented Container) mad...
Gaseous elemental and reactive mercury in Southern New Hampshire
Gaseous elemental reactive mercury Southern New Hampshire
2009/3/31
We conducted measurements of Hg0 and RGM at two inland sites, Thompson Farm (TF) and Pac Monadnock (PM), and a marine site (Appledore Island (AI)) from the UNH AIRMAP observing network in New Hampshir...
In situ measurements of speciated atmospheric mercury and the identification of source regions in the Mexico City Metropolitan Area
speciated atmospheric mercury source regions Mexico City Metropolitan Area
2009/3/12
In order to expand the currently limited understanding of atmospheric mercury source-receptor relationships in the Mexico City Metropolitan Area, real time measurements of atmospheric mercury were mad...
A numerical modelling study on regional mercury budget for eastern North America

2009/3/10
In this study, we have integrated an up-to-date physio-chemical transformation mechanism of Hg into the framework of US EPA's CMAQ model system. In addition, the model adapted detailed calculations of...
Modelling of Mercury in the Arctic with the Danish Eulerian Hemispheric Model
Mercury Arctic Danish Eulerian Hemispheric Model
2009/3/10
A new 3-D mercury model has been developed within the Danish Arctic Monitoring and Assessment Programme (AMAP). The model is based on the Danish Eulerian Hemispheric Model, which in the original versi...
The fate and transport of mercury over Europe is studied using a regional Eulerian transport model. Because gaseous elemental mercury is a long-lived species in the atmosphere, boundary conditions mus...
Circumpolar transport and air-surface exchange of atmospheric mercury at Ny-Ålesund (79° N), Svalbard, spring 2002
Circumpolar transport atmospheric mercury Svalbard
2008/11/27
Mercury in different environmental compartments has been measured at Ny-Ålesund (78°54' N, 11°53' E) during an intensive campaign, 17 April to 14 May 2002. Time-resolved speciated determination ...
A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow
