At present, Sweden has 4 integrated monitoring (IM) sites that are part of a European network on integrated monitoring with an extensive measurement program. One of these sites, Gammtratten, situated in central Västerbotten, monitors several variables. This program is part of the International Cooperative Programme (ICP) on Integrated Monitoring (IM) of Air Pollution Effects on Ecosystems In Sweden there are three IM-sites, out of which Gammtratten in northern Sweden is one. The IM program at Gammtratten is performed by a consortium including IVL, SGU and SLU-EA. Basically there are three types of monitoring at the IM-sites, viz. Climatic, Chemical and Biological observations.

1. The WMO facilitates worldwide cooperation in the establishment of networks of stations for the making of meteorological observations as well as hydrological and other geophysical observations related to meteorology. Observing stations are operated by WMO Members according to agreed standards and recommended practices described in the WMO Regulatory Material, such as Technical regulations, WMO-No. 49 and its Annexes.

2. The WMO requirements for observational data are generally divided into three categories: global, regional and national. For example, surface synoptic stations are expected to report every six hours for global exchange and every three hours for regional exchange, however with higher frequency on bilateral and multilateral arrangements. The details of the observational programmes provided by all stations operated by WMO Members are given in the WMO Observing Systems Capability Analysis and Review Tool (OSCAR) and available on the WMO website at https://oscar.wmo.int/OSCAR/index.html#/.

3. The approved operational procedures and practices are given in the regularly updated Manual on the Global Observing System (WMO-No. 544), and the Manual on the WMO Integrated Global Observing System (WMO-No. 1160) available also on the WMO website at http://www.wmo.int/pages/prog/www/OSY/Manuals_GOS.html and http://www.wmo.int/pages/prog/www/wigos/documents/WIGOS-RM/1160_en.pdf, respectively.

4. Under the Global Observing System of the World Weather Watch Programme, WMO Members operating stations in the Arctic Monitoring and Assessment Programme (AMAP) area (essentially includes the terrestrial and marine areas north of the Arctic Circle (66°32N), and north of 62°N in Asia and 60°N in North America, modified to include the marine areas north of the Aleutian chain, Hudson Bay, and parts of the North Atlantic Ocean including the Labrador Sea), contribute to the implementation of the observational programme by operating 336 surface Regional Basic Synoptic and 156 Regional Basic Climatological stations. A detailed infomration is available through WMO OSCAR: https://oscar.wmo.int/OSCAR/index.html#/. 

Aerosols, Clouds, and Trace gases Research InfraStructure - ACTRIS  is a research infrastructure on the ESFRI roadmap from March 2016. ACTRIS is currently supported by the European Commission Horizon 2020 Research and Innovation Framework Programme (H2020-INFRAIA-2014-2015) from 1 May 2015 to 30 April 2019.

The objectives of ACTRIS Research Infrastructure

Detecting changes and trends in atmospheric composition and understanding their impact on the stratosphere and upper troposphere is necessary for establishing the scientific links and feedbacks between climate change and atmospheric composition.

• The primary objective of ACTRIS is to provide the 4D-variability of clouds and of the physical, optical and chemical properties of short-lived atmospheric species, from the surface throughout the troposphere to the stratosphere, with the required level of precision, coherence and integration.
• The second objective is to provide effective access to this information and the means to more efficiently use the complex and multi-scale ACTRIS parameters serving a vast community of users working on models, satellite retrievals, and analysis and forecast systems.
• The third objective is to raise the level of technology used in the RI and the quality of services offered to the community of users, involving partners from the private sector.
• Finally, the fourth objective of ACTRIS is to promote training of operators and users and enhance the linkage between research, education and innovation in the field of atmospheric science.

The main objective is to quantify the levels of air pollution in the artctic, and to document any changes in the exposures. It includes the necessary components to address impacts on ecosystems, human health, materials and climate change. 

The main mission of the International Arctic Systems for Observing the Atmosphere (IASOA) is coordination of atmospheric data collection at existing and newly established intensive Arctic atmospheric observatories. Data of interest to the IASOA consortium include measurements of standard meteorology, greenhouse gases, atmospheric radiation, clouds, pollutants, chemistry, aerosols, and surface energy balances. These measurements support studies of Arctic climate change attribution (why things are changing), not just trends (how things are changing). IASOA is responsive to growing evidence that the earth system may be approaching environmentally critical thresholds within decadal time scales. The information from IASOA will not only enhance scientific understanding but will also support decisions by the global community regarding climate change mitigation and adaptation strategies. Main gaps: Not all observatories are members of established global networks such as GAW and BSRN. It is recommended that IASOA observatories that are not members of these global networks be evaluated for potential membership and that roadblocks to membership be investigated. Other types of measurement gaps include, but are not limited to: (1) Radar-lidar pairs at each observatory to assess cloud properties; (2) Flux towers at each observatory for methane and CO2 fluxes; (3) Aerosol measurements at each observatory; and (4) Surface and upper air ozone measurements at each observatory. Network type: Predominantly atmospheric measurements.

The Arctic region represents a sensitive ecosystem, which is susceptible to even small changes in the local climate. Special conditions of usually high surface albedo and low solar elevations cause enhanced aerosol/cloud effects due to multiple scattering. It is suspected that this increased interaction between solar radiation and the aerosol particles/clouds magnifies their radiative impact. Thus, for a given aerosol distribution, the specific optical properties are enhanced in the polar regions. For the same reasons, results from field experiments at low latitudes are difficult to transfer to polar regions and as a consequence there is an urgent need to conduct specific measurement programs in high latitude regions. In order to improve the knowledge about the origin, transport pathways, vertical structure of aerosol physical and chemical properties as well as the impact on climate in the polar regions, a combined effort of surface-based, airborne and spaceborne measurements is needed. Therefore, this proposed project is aiming at a determination of the vertical structure of the chemical, physical and optical properties of Arctic aerosol particles, including solar radiative closure between observed and calculated aerosol properties (direct climate effect)

Both NOAA and NASA operate satellites with cover¬age of the Arctic region. The major observations and products are: 1. Daily, near real-time plots of surface, cloud, and radiative properties from AVHRR; 2. Near real-time MODIS and AVHRR polar winds; 3. Daily, near real-time plots of clear sky, low-level temperature inversions from MODIS; 4. Daily profile plots of Arctic temperature, humid-ity and winds; 5. Near-daily plots of surface winds over open water; and 6. Surface temperatures for land, sea and sea ice.
