Surface air temperature from meteorological data
Here an archive on monthly and annual mean surface air temperature measured at the 2 m height at meteorological stations to the north of 60o N is placed. Geographical positions of the stations are shown in the map. The chosen stations have the longest observational records.
Collected surface air temperature data indicate substantial fluctuations in the high northern latitudes on decadal to multi-decadal time scales, including pronounced two warm periods: the 1920s-1940s and since the 1970s.    more    >>

Annual temperature at the shown stations to the north of 60deg.N over the globe

Analysis of surface air temperature temporal variability (including frequency structure of temperature variability and separate investigation of variability during the periods of warming and cooling) can be found here. Examples of temperature time series analysis using correlation, fractal and mulifactor analysis are collected in data analysis section. Analysis of simulated and observed temperature change in different Arctic regions and principal component analysis of near surface air temperature anomalies can be found here.

Besides, you have an access to temperature data at 13 stations in the North West region of Russia, including Kola Peninsula, Republic of Karelia, the eastern part of Arkhangelsk district and the northern part of Leningrad district. For the region as a whole, a noticeable increase of annual air temperature during the XX century was detected. To look at a full analysis of temperature data for NW Russia please go to regional analysis section of the CLIMAS web site.
