Wave energy and mean wave direction resolved into 9 bands

As requested by the US Army Corps of Engineers, CDIP has special data formats for wave energy and direction.
9-bands: 2-6, 6-8, 8-10, 10-12, 12-14, 14-16, 16-18, 18-22 & 22+ seconds
Spectral processing performed on 1600-second samples
For each band, equivalent Hs = 4*sqrt(Band Energy)
Wave direction in each band represents the average, in support of coastal process studies
