Sea-ice development in the Arctic Following 2020, a year that managed to break a number of records in the Arctic, the new year has begun less spectacularly, as a closer examination of the months Decem
These include data on sea-ice formation and dynamics in the Antarctic pack-ice belt. When the Federal Republic of Germany became a signing member of the Antarctic Treaty in 1979 and established the Ge
The meteorological seasons are always three complete months long. The reason: so that, for the purposes of climatological assessments, only data for entire months has to be taken into account (e.g. th

A time-lapse video of the MOSAiC expedition – a one-of-a-kind sequence compiled using a selection from ca. 2.5 million radar images. One of these systems was kept running nonstop throughout the MOSAiC
Not until the end of the month did the sea-ice extent substantially decline, dropping below two standard deviations from the average for the period 1981 – 2010. At the same time, the summer solstice w
The stratosphere is the part of our atmosphere beginning at an altitude of ca. 10 km, and where, thanks to the absorption of the trace gas ozone, temperatures rise with increasing altitude. Normally,
While the summer minimum was reached in the Antarctic on 19 February 2020 (at 2.68 million km²), in the Arctic the extent has been growing steadily since the end of February, and hasn’t yet reached it
