Sea ice drift and surface temperature were measured by the Compact Air-Launched Ice Beacon (CALIB) 2020C41 drifting on Arctic sea ice deployed via aircraft gravity launcher during IceBird MOSAiC. The time series describes the position and additional parameters of the buoy between 08 September 2020 and 30 November 2020 in sample intervals of 1 hour. This buoy got deployed on 2020-09-08T12:02:20 at 83.57363 N and 6.4244 E. However, first data of this buoy was received on 2020-09-10T18:00:00 at 83.5638000 N and 4.5764000 E. ... : The data set has been processed, including the flagging of obvious inconsistencies in position. The position is flagged if the drift velocity exceeds a threshold (Quality flag, position = 1), if the position exceeds extreme values, such as longitude > 360 deg (Quality flag, position = 2), and if the position is exactly 0.0 (Quality flag, position = 4). These quality flag values can be sums of each other. ...
