The purpose of the Sustaining Arctic Observing Networks (SAON) is to support and strengthen the development of multinational engagement for sustained and coordinated pan-Arctic observing and data sharing systems. SAON was initiated by the Arctic Council and the International Arctic Science Committee, and was established by the 2011 Ministerial Meeting in Nuuk.
The SAON inventory builds on a survey circulated in the community at the inception of the activity. This database is continously updated and maintained, and contains projects, activities, networks and programmes related to environmental observation in the circum-polar Arctic.

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
