First, I want to thanks the IABP project for providing data.
The date of buoy data is from 2018 to 2022. I used the buoys from IABP Arctic programme to generate the drift of sea ice, actually, IABP provide buoys which arer set by multi project such as MOASIC etc. So, I cannot say the buoy is only from IABP.
2, 3, 6 in file name represent the time interval. The 2 means uses the location of buoy in 00：00 to 00:00 in the two days after for generate drift. The unit of speed is m/s.
