Sea ice drift and surface temperature from autonomous measurements from buoy 2021C40, deployed during MELTEX 2021


Sea ice drift and surface temperature were measured by the Compact Air-Launched Ice Beacon (CALIB) 2021C40 drifting on Arctic sea ice deployed by air-plane drop off during MELTEX 2021. The time series describes the position and additional parameters of the buoy between 29 Jul 2021 and 24 Dec 2022 in sample intervals of 1 hour. 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.
