Measurements of climate-influencing substances on Svalbard

Updated 2011-02-15

National Environmental Monitoring in Sweden in the "Air" programme and sub-programme "A Protective Ozone Layer" (the thickness of the ozon layer). 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 proceed over Spitzbergen (Svalbard). The mesurements include carbon dioxide (CO2)-continuously, carbon monooxid (CO)and methane (CH4) weekly. The particle size distribution, concentration, light absorption - continuously and light scattering measurments - daily.

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 ITM SU website: Environmental monitoring methods are described also on Swedish EPA website (

Additional Information

Is this a bi- AND multi-lateral project (i.e. a project involving cooperation between different countries)?
Other institutes involved in the project

Norwegian Institute for Air Research (NILU); World Meterological Organization (WMO) central laboratory; Swedish EPA.

Is this project reporting to other organizations/programmes?

The data are reported to the World Meterological Organization (WMO) and Department of Energy Organization (DEO), Swedish EPA. The Swedish Zeppelin data are reported to several regional, national and global monitoring networks such as World Data Center for Greengouse Gases (WDCGG), and CarboEurope-IP.
