Chu US Navy/Naval Postgraduate School pcchu@nps.edu resourceProvider US Navy/Naval Postgraduate School resourceProvider Chu, Peter C. US Navy/Naval Postgraduate School pcchu@nps.edu author US Navy/Naval Postgraduate School author tableDigital This dataset comprises 3D gridded climatological fields of geostrophic velocity inverted from World Ocean Atlas-2013 (WOA2013) temperature and salinity fields using the P-vector method. It provides a climatological velocity field that is dynamically compatible to the WOA2013 (T, S) fields. The dataset has the same spatial resolution and temporal variation (annual, monthly, seasonal) as WOA2103 (T, S) fields, but does not cover the equatorial zone (5oS – 5oN) due to the geostrophic balance being the theoretical basis for the P-vector inverse method. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0121576 Preview graphic PNG 0121576 NCEI ACCESSION NUMBER 2014-08-21 publication CURRENT SPEED - EAST/WEST COMPONENT (U) CURRENT SPEED - NORTH/SOUTH COMPONENT (V) theme NODC DATA TYPES THESAURUS derived products theme NODC OBSERVATION TYPES THESAURUS US Navy/Naval Postgraduate School dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS World-Wide Distribution place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NODC > National Oceanographic Data Center, NESDIS, NOAA, U.S. Department of Commerce DOD/USNAVY/NPS > Naval Postgraduate School, U.S. Navy, U.S. Department of Defense dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
