FNMOC 500 mb Geopotential Height, 360x181, Monthly

Published by NOAA NMFS SWFSC Environmental Research Division | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-09-04T00:00:00.000+00:00
Monthly means of the FNMOC (Fleet Numerical Meteorology and Oceanography Center) 6-hourly analyzed geopotential height field on a 360 by 181 global spherical grid (1 degree). For more information on the models used to compute these data please see: Rosmond, T. E., 1992: A prototype fully coupled Ocean-Atmosphere Prediction System, Oceanography Vol. 5, No. 1, 25-30. Clancy, R. M., 1992: Operational Modeling: Ocean Modeling at the Fleet Numerical Oceanography Center, Oceanography Vol. 5, No. 1, 31-35. 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.
