We evaluate the sensitivity of Bry entering the stratosphere with a simplified model that allows calculations over a wide parameter range for parameters that are currently poorly quantified. The model...
Pathways of PFOA to the Arctic: variabilities and contributions of oceanic currents and atmospheric transport and chemistry sources
PFOA the Arctic oceanic currents atmospheric transport chemistry sources
2010/10/21
Perfluorooctanoic acid (PFOA) and other perfluorinated compounds are industrial chemicals in use for decades which resist degradation in the environment and seem to accumulate in polar regions. Transp...
Long-term trends of black carbon and sulphate aerosol in the Arctic: changes in atmospheric transport and source region emissions
black carbon sulphate aerosol the Arctic atmospheric transport source region emissions
2010/10/11
To reveal the contribution of different source regions on these trends, we used a cluster analysis of the output of the Lagrangian particle dispersion model FLEXPART run backward in time from the meas...
