USACE "9 band" DATA FORMATS
As requested by the US Army Corps of Engineers, CDIP has special data formats for wave energy and direction. There are also CDIP specific formats for other data types such as wind and barometric pressure.
Wave energy is resolved to 9 bands (2-6,6-8,8-10,10-12,12-14,14-16,16-18,18-22,22+ seconds) in units of cm^2. (Please see the confidence interval disclaimer below).
The mean wave direction is resolved to 9bands (as above). Harvest Platform only has 6 period bands due to the large distance between sensors. Angles reported in the directional data are true compass headings towards which the waves are traveling at the location of the measuring instrument. Peak direction is given in the second column.
