VIRGINIA BEACH OFFSHORE, VA - 171 Classic View

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

Data Access

Data Use and Acknowledgements

THREDDS Server

A web server that provides metadata and data access for CDIP's NetCDF datasets, using OPeNDAP, OGC WMS and WCS, HTTP, and other remote data access protocols.

NDAR

A web utility for accessing data from CDIP's NetCDF data files. It serves station data in traditional CDIP formats, as well handling newer formats and wavecdf datasets from any source.

ERDDAP™

ERDDAP™ (the Environmental Research Division's Data Access Program) is a data server that gives you a simple, consistent way to download subsets of scientific datasets in common file formats and make graphs and maps.
