Two full years' data .from an automatic weather station sited at Robertskollen, Dronning Maud Land, Antarctica are presented. Air temperature and humidity, wind speed and direction, three types of radiation and the temperature of three microhabitats of biological significance were collected. Minimum air temperatures were higher during the winter, when compared with previously collected data from the South African station, SANAE III. The maximum air temperature recorded was 5,2 癈 whereas soil temperatures reached 34,4 癈. The average weekly temperatures of the microhabitats remained above freezing from mid- November to early February. The absolute minimum temperature (-33,6 癈) was the same for air and all microhabitats. Implications for the biota living in these habitats are briefly discussed.
