Atmospheric gaseous elemental mercury (GEM) concentrations and mercury depositions at a high-altitude mountain peak in south China
Atmospheric gaseous elemental mercury concentrations mercury depositions high-altitude mountain peak
2010/3/16
China is regarded as the largest contributor of mercury (Hg) to the global atmospheric Hg budget. However, concentration levels and depositions of atmospheric Hg in China are poorly known. Continuous ...
Hydrogen cyanide in the upper troposphere: GEM-AQ simulation and comparison with ACE-FTS observations
Hydrogen cyanide GEM-AQ simulation ACE-FTS
2009/7/15
We investigate the spatial and temporal distribution of hydrogen cyanide (HCN) in the upper troposphere through numerical simulations and comparison with observations from a space-based instrument. To...
GEM/POPs: a global 3-D dynamic model for semi-volatile persistent organic pollutants – Part 2: Global transports and budgets of PCBs
3-D dynamic model semi-volatile persistent organic pollutants transports PCBs
2008/12/16
Global transports and budgets of three PCBs were investigated with a 3-D dynamic model for semi-volatile persistent organic pollutants – GEM/POPs. Dominant pathways were identified for PCB transports ...
GEM/POPs: a global 3-D dynamic model for semi-volatile persistent organic pollutants – Part 1: Model description and evaluations of air concentrations
GEM/POPs 3-D dynamic model semi-volatile persistent organic pollutants air concentrations
2008/12/16
GEM/POPs was developed to simulate the transport, deposition and partitioning of semi-volatile persistent organic pollutants (POPs) in the atmosphere within the framework of Canadian weather forecasti...
GEM-AQ, an on-line global multiscale chemical weather modelling system: model description and evaluation of gas phase chemistry processes
GEM-AQ gas phase chemistry processes
2008/11/11
Tropospheric chemistry and air quality processes were implemented on-line in the Global Environmental Multiscale weather prediction model. The integrated model, GEM-AQ, was developed as a platform to ...
Formation and transport of photooxidants over Europe during the July 2006 heat wave – observations and GEM-AQ model simulations
formation transport photooxidant heat wave observations GEM-AQ model
2008/10/29
The European heat wave of July 2006 was caused by advection of very hot and dry air from North Africa. Air masses were transported on the western edge of the high pressure system, centred over Eastern...
