Fig. 3.

Observed vertical velocities in north and northeast Greenland. Symbols and related information are explained in the caption to Fig. 1. Here, as in Figs. 1 and 2, if the four-letter station code appears in grey it means that a velocity solution is not yet available because technical problems led to a total observational timespan of less than one year. The standard error estimates for velocity vary with the timespan of observation (SI Appendix, Table S1) but are nearly always < 1 mm/yr.
