21. Abisko Scientific Research Station (ANS) (ANS)

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.

22. SLU, Faculty of Forestry, Unit for Forest Field Research, experimental forests

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.

23. SMHI Climate monitoring

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

24. Millimetre wave radiometer for stratospheric trace gas measurements

A millimeter wave radiometer is started operation at the Swedish Institute of Space Physics, Kiruna, Sweden. The location of the instrument (67.8 N, 20.4 E) allows continuous observation of the evolution of ozone and ozone related trace gases in the Arctic polar stratosphere. It is designed for measurements of thermal emission lines around 204 Ghz. At this frequency observations include of ozone, chlorine monoxide, nitrous oxide, and nitric acid.

25. Differential Optical Absorption Spectrometer

The DOAS instrument consists of grating spectrometer covering the visible and near ultraviolet spectral region. Zenith-scattered sunlight is collected by simple one-lens telescopes and fed via optical fiber bundles into the spectrometers, where atmospheric absorption spectra are obtained. The instrument runs automatically. Total column densities of the stratospheric trace species ozone, NO2, BrO, and OClO are retrieved from the spectra using the DOAS algorithm. These are species that play a major role in ozone chemistry, either by themselves in ozone destruction (BrO) or as indicators of chlorine activation/deactivation (OClO). The chemistry and dynamics of ozone destruction is investigated, e.g. with respect to the location of the polar vortex during the winter. The instrument is also useful for detection of polar stratospheric clouds using the zenith-sky colour index method.

30. Long-Term and Solar Variability effects in the Upper Atmosphere

Objective: to determine how solar activity influences temperatures, winds, electric currents and minor constituents and to allow possible anthropogenic influences to be determined. Uses primarily measurements by the ESRAD and EISCAT radars, plus ground-based and balloon-borne measurements of atmospheric electric fields and currents.

31. Swedish Regional Climate Modelling Programme (SWECLIM)

It has become clear in recent years that a changing composition of the atmosphere due to human activities may influence the climate system. The production of greenhouse gases and their accumulation in the atmosphere can result in a global warming and changes in the climate system. On regional scales, this may result in even much more pronounced changes. This is particularly true for the high northern latitudes. Climate changes will impact the society and nature in many ways. The anticipated effects are large and will matter both globally (mainly negative consequences) and regionally (both negative and positive consequences). SWECLIM provides users with detailed regional climate study results. SWECLIM develops regional (limited area) climate system modeling, studies climate processes and feedback special for the Nordic region and creates regional climate (change) scenarios on a time scale of 50-100 years. SWECLIM also performs impact studies on water resources. Climate scenarios are also made available for other impact studies, such as in forestry, done by external groups. Information activities on climate change and the regional consequences are an important component in the program. The regional climate model system is built around a regional atmospheric model, regional ocean models with sea ice for the Baltic Sea and land surface modeling plus hydrology. The model system is forced at the by large-scale results from global climate models. Multi-year to multi-decade length integrations are performed with the regional model targeting a domain roughly centered on the Nordic countries and using horizontal resolutions ranging from 20-80 km.
