Abstract:
Sea ice drift was measured by Surface Velocity Profiler 2020P225, aka Pos_PRIC_20, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 3) 2019/20. The time series describes the position and additional parameters of the buoy between 23 April 2020 and 11 November 2020 in sample intervals of 1 hour.

Comment:
The data set has been processed and contains quality flags for different kinds for erroneous data. Flag values are the sum of individual error codes. The value of 0 refers to no error.
Quality flag, position: The geographic position is flagged +1 if the drift velocity, as derived from the GPS longitude and latitude, exceeds a threshold of 10 deg latitude or 50 deg longitude per time step; +2 if the position exceeds extreme values, such as longitude > 360 deg; +4 if the position is exactly 0.0.
