General information and objectives
- To determine the main physical and chemical processes responsible for the occurrence and accumulation of acidic and aerosol components in the high alpine region.
- To investigate the contribution of various source regions to the deposition of trace components and their geographical and seasonal trends.
Field study in the high alpine region measuring:
Highlights of ALPTRAC current scientific results
Snow samples are now routinely taken at 15 sites between 2450 and 3900 m over a 650 km stretch of the Alps. There is clear evidence for an increase in acid deposition, both sulphuric and nitric acids, over the Alps this century, with a striking increase, west to east, by a factor of between 2 and 3. ( Although this increase may be due to greater deposition in the east, a possible dilution effect in the west, where more snow fell, needs to be taken into account.) A complete description of the stations and their activities is published in the ALPTRAC Data Catalogue, a EUROTRAC Special Publication.
