Dear Thomas,
Thank you for your query. It is not necessary to open a trac ticket

sea_ice_y_displacement [m]
'Displacement' means the change in geospatial position of an object that
has moved over time. The time interval during which the motion took
place must be specified using a bounds variable for the time coordinate
variable. A displacement is a vector quantity. Sea ice displacement is
defined as a two-dimensional vector, with no vertical component. "y"
indicates a vector component along the grid x-axis, when this is not
true longitude, positive with increasing y. A y displacement is
calculated from the difference in the moving object's grid y coordinate
between the start and end of the interval given in the time bounds
variable.
Hi Alison,
I think I spotted a cut-and-paste error in the above description. I
assume that it should be "y-axis" instead of "x-axis"?
Otherwise, the descriptions seem clear and reasonable to me. :-)
Best wishes,
Philip
