Directory entires that have specified Zeppelin mountain Atmospheric Research Station as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada).

Arctic study of trophospheric aerosol, clouds and radiation
One of the major benefits of performing measurements at Ny-Ålesund is the availability of a monitoring station on Mount Zeppelin, 474m asl. Given the typical height of the Arctic inversion layer during the envisaged measurement period, it will be possible to continuously monitor mercury and particulate in the free troposphere at the same time as performing ground level monitoring. The simultaneous measurements above and below the boundary layer should provide evidence for the mode of elemental Hg replenishment, whether it is from due to exchange with the free troposphere, or transport occurring at sea level. The proposed collaboration, by collecting data from two strategically placed Arctic stations, in the paths of different air masses and data from above the Arctic inversion layer would provide the most comprehensive set of Arctic mercury measurements performed to date.
The major goal of the process study between April 15 and May 15, 2003 is to obtain quantified information on reaction path-ways, products and net deposition of mercury during Arctic sunrise.
