Abstract:
Sea ice drift and surface temperature were measured by the Compact Air-Launched Ice Beacon (CALIB) 2017C19 drifting on Arctic sea ice deployed via aircraft gravity launcher during TIFAX 2017. The time series describes the position and additional parameters of the buoy between 22 August 2017 and 06 March 2020 in sample intervals of 1 hour.

Comment:
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.
