Measurements of climate-influencing substances on Svalbard

Updated 2017-10-19

National Environmental Monitoring in Sweden in the "Air" programme. The objective of the project is to follow climate-changing gases and particles and which effects they could have on the climate of earth. To understand and assess the human effect on the climate, regionally and globally, the atmospheric aerosols and greenhouse gases are monitored. The project aims follow: (i) detecting long-term trends in the carbon dioxide level, as well as trends in the amount or composition of aerosols in the background atmosphere; (ii) provide a basis to study the processes that control the aerosol life cycle from their formation through aging and transformation, until being removed from the atmosphere; (iii) provide a basis to study the processes (sources, sinks, and transport pathways) that control the level of carbon dioxide in the atmosphere; (iv) contribute to the global network of stations that perform continous measurements of atmospheric particles and trace gases to determine their effect on the earths radiation balance and interaction with clouds and climate.

This is not a National Implementation Plan (NIP) project
Comments and additional information:

The project observations are preformed over Spitzbergen (Svalbard). They include continuous measurements of carbon dioxide (CO2) and weekly measurements of carbon monoxide (CO) and methane (CH4). The particle size distribution, concentration and light absorption is measured continuously and light scattering is measured daily.  Weekly measurements of the amount of elemental and organic carbon (EC/OC) are also performed by Stockholm University, Department of Environmental Science and Analytical Chemistry (ACES). Continuous measurements of CO2 have been conducted together with the Norwegian Institute for Air Research (NILU) since 2014.

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

Carbon dioxide and other compounds are measured few times per 24hours; CO2, methan, isotopes in carbon dioxide one time per week. Sampling and analysis are according to international inter-calibration methods. More details on ACES website:

Environmental monitoring methods are described also on Swedish EPA website (in Swedish):(

Analyses and sampling are preformed according to standards and recommendations from EMEP, EUSAAR/ACTRIS and NOAA.
