Calculating deposition in a grid over Sweden showed the lack of information on deposition at high altitude. SMHI applied the meso scale MATCH model to calculate the deposition field and the matched model is called MATCH-Sweden. The result is found at http://www.smhi.se/cmp/jsp/polopoly.jsp?d=5640&l=sv The observations made at these stations are: Particles in air: SO4-S, NO3-N, NH4-N, Cl, Na, Ca, Mg, K Gase:s NH3-N, HNO3-N, SO2-S Deposition open field precipitation: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K Deposition in forest throughfall: H+, SO4-S, Cl, NO3-N, NH4-N, Ca, Mg, Na, K To integrate the relatively few deposition measurement sites, SMHI has adopted the Mesoscale Atmospheric Transport and Chemistry Model (MATCH) that uses emission data, meteorological data, routines for chemical processes, and a transport model to calculate long-range transport and deposition of air pollutants (Table 4, #1.5). Time series of gridded data over Sweden for deposition of different inorganic chemical compounds calculated with the MATCH-Sweden model are available at SMHI (Appendix, Table 11). When the MATCH-Sweden model was first tested, the deposition network lacked high elevation sites. Hence, a monitoring program for deposition at higher elevations (Table 4, #1.9) was started. It consists of 4 sites in high elevation forests along the Swedish mountain ridge, where NO3, NH4, NH3, HNO3, SO2, SO4, Na, K, Ca, Mg, Cl, pH, conductivity, and amount of precipitation are analyzed on monthly accumulated precipitation samples.
The subprogram main task is to check if international agreements as the UN Convention on Long Range Transboundary Air Pollution (CLTRAP) are followed. EMEP = European Monitoring and Evaluation Programme. The network comprises 10 stations, out of which three are in northern Sweden. Air chemistry is monitored by diffusion samplers. The following compounds are measured: SO2, SO4, tot-NH4, tot-NO3, soot, NO2, O3 Precipitation quality is monitored by samplers with lid, open only when it rains. The following compounds are measured: SO4-S, NO-N, Cl, NH4-N, Ca, Mg, Na, K, pH, EC. Ozone near ground is analyzed every hour and is part of an European warning system PM10 is particles Metals in air and precipitation is analysed at Bredkälen only. The following elements are analyzed: As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, V, Hg, metyl-Hg.
The PMK Network is part of the national network for deposition measurements. The aim is a longterm monitoring concentration and deposition of different air transported compounds. The aim is also to generate knowledge about longterm variation in the deposition field, and to give background data from low polluted areas for calculation of pollution deposition in more polluted areas. The Air and Precipitation Chemistry Network includes about 25 sites (14 in northern Sweden) where precipitation from open accumulating samplers are collected and analyzed for pH, SO4, NO3, NH4, Cl, Ca, Mg, Na, K, conductivity, and amount of precipitation (Table 4, #1.2). At 3 sites (one in northern Sweden) precipitation is analyzed for heavy metals, mercury, and methyl-mercury (Table 4, #1.3).
At the top of the micrometeorological tower (102 m) at Norunda north of Uppsala, carbon dioxide and methane concentrations are also measured.
at the Institute for Space Physics (IRF) in Kiruna, an automated weather station logging air temperature, humidity, wind, pressure, and UV-radiation has been in operation since 1996
Investigations within many areas of biosciences and geosciences are carried out at the station. The emphasis of staff research is on plant ecology and meteorology. The main objectives of the ecological projects are to study the dynamics of plant populations and to identify the controlling factors at their latitudinal and altitudinal limits. The meteorological projects deal with recent climate changes in the region, and also with local variations of the microclimate in subalpine and alpine ecosystems.
The Faculty of Forestry at SLU has two research stations with experimental forests, two experimental forests with permanent staff, three without permanent staff and a large number of long-term field trials. These facilities are spread over the country.
The Swedish Meteorological and Hydrological Institute (SMHI) performs basic climate measurements (Table 2 and Table 6, #1) in an irregular grid over the country (Fig. 1). For non-commercial research and educational purposes, data from the core services are made available at handling costs only. The meteorological base network (Table 6, ##1.1–1.6) north of 60°N consists of 105 stations; Table 2 lists the different observation programs. In addition to the meteorological base network, SMHI operates several other climate stations with a variety of instrumentation. Main gaps: The meteorological base network was biased toward lowland in populated areas, originally because potential observers were more likely to be found there. This problem has been partly overcome since the introduction of automated sampling systems. Still there has been a need for climate measurements in forested areas on higher grounds. Network type: National monitoring
