It is important to monitor the atmospheric climate to reveal the effects of increases in greenhouse gases in the atmosphere. Atmospheric radiation, temperature, precipitation and the amount of greenhouse gases in the atmosphere are key climate indicators. Since there are large natural variations in the Arctic, it is important to monitor the climate indicators over a long period.
