Directory entires that have specified Finland 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).

This project is now part of the project: Acidifying and Eutrophifying Substances in Air and Precipitation
National Environmental Monitoring Programme. National Environmental Monitoring Programme. The PMK Network is part of the national network for deposition measurements. The aim is (i) a long-term monitoring of concentration and deposition of selected air transported compounds caused acidification and eutrophication in different parts of Sweden; (ii) to generate knowledge about long-term variation in the field deposition, (iii) to give the background data from low polluted areas for calculation of pollutants deposition in more polluted areas the monitoring of pollutants in air and precipitations are proceed. Ozon and air samples for analysis of sulphur and nitrogen compounds, HCl as well as basic metal ions (Na, K, Ca, Mg, are taken on a monthly basis in air and precipitation. Ozone, as well as sulphur and the nitrogen compound particles are measured in air, and sulphur and nitrogen compounds, base cations, pH and electro-conductivity in precipitation.
The main objective of the facility is to enhance the international scientific co-operation at the seven Finnish research stations and to offer a very attractive and unique place for multidisciplinary environmental and atmospheric research in the most arctic region of the European Union. Factors such as, arctic-subarctic and alpine-subalpine environment, northern populations, arctic winters with snow, changes in the Earth's electromagnetic environment due to external disturbances and exceptionally long series of observations of many ecological and atmospheric variables should interest new users.
