Model forcing validation: Model forcing validation: Air temperature, humidity, SLP, wind, SLP, cloudiness from NCAR/NCEP Air temperature, humidity, SLP, wind, SLP, cloudiness from NCAR/NCEP can be validated based on North Pole stations can be validated based on North Pole stations

Sea Level data sources
Monthly mean relative sea levels were provided by the Arctic and Antarctic Research Institute for 71 stations (see station numbers) located in the Barents and Siberian Seas. The time series of sea level variability generally cover the period between 1948 and 2008 but temporal coverage differs significantly from station to station. Red denotes stations with the most complete datasets. The best data are available from 9 stations (blue circles) for the period 1954 – 2008.
