Scroll downward through this document to see time series plots, a progressive vector diagram, frequency histograms, and a KE spectrum from this current meter.
The axes of the PVD are labelled in kilometers. Boxes mark the beginning of each month. This PVD was made from a version of the current record in which the gaps in u and v were filled by interpolation.
From here you can either move up one level or go back to the top window.
