Global monthly derived winds can be obtained for any point on the ocean

(Northern Hemisphere: 1967 - present, Southern Hemisphere: 1981 - present).

ERD was established at the U.S. Navy Fleet Numerical Meteorology and

Oceanography Center (FNMOC) to take advantage of the Navy's global

oceanographic and meteorological databases. FNMOC produces operational

forecasts of the state of the atmosphere and the ocean several times daily

and maintains archives of several important parameters, such as sea level

pressure and temperature. ERD derives a number of well-known environmental

data and index products which are routinely distributed to researchers at

many state and federal laboratories, as well as to academic and international

researchers.
