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.

CO2, CO, CO4, particle concentration, light dispersion, particle size distribution, light absorption, and light scattering. In addition flask samples are analyzed for: CO2-13, H2, N2O, SF6 and O-18 in CO2.

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: http://www.aces.su.se/zeppelin/measurements.html
Environmental monitoring methods are described also on Swedish EPA website (in Swedish):(http://www.naturvardsverket.se/Stod-i-miljoarbetet/Vagledningar/Miljoovervakning/Handledning/Metoder/Programomrade-Luft/)
Analyses and sampling are preformed according to standards and recommendations from EMEP, EUSAAR/ACTRIS and NOAA.
