a Horizontal distribution of harmonic dial vectors over the tropical Pacific and Atlantic ocean for (red) L2(T) from temperature measurements (38 stations), (blue) L2(Tad) from pressure measurements (7 stations), and (light-blue) L2(Tad) from grid dataset by SD16. b–f As (a) but for selected longitudes; only the end points of harmonic dial vectors plotted with the error bars
