Meteorological observations were made at the drifting ice station Tara in the central Arctic Ocean from 23 March to 19 September 2007, constituting a unique data set from the season preceding the record-low sea ice extent. Comparisons of the Tara data with observations at the Russian drifting ice stations in 1937-1938 and 1950-1991 and at SHEBA in 1998 indicated that at Tara and SHEBA the atmospheric transmissivity for shortwave radiation was smaller than at the Russian stations, suggesting a higher cloud fraction or optical thickness. Compared to the mean conditions at the Russian stations, at Tara the melting season was twice as long and in April the 2-m air temperature was 7.0°C higher, but in July the 2-m temperature difference disappeared. The Tara tethersonde sounding data suggest that the air temperature at the altitudes of 200-1000 m was approximately 1°C higher than the mean of 1954-1985.
