These grids have been assembled by DSS from the grids of various meteorological chart digitization projects and operational analyses [https://rda.ucar.edu/OS/web/datasets/d010000/docs/data_sources]. Grids begin in 1899 and cover the Northern Hemisphere from 15N to the North Pole. The dataset continues to be updated regularly as new data become available. In the earlier years, there is one grid per day, but from July 1962 on, there are two grids per day. Prior to 1946, the original grids had a 10-degree resolution and the intermediate points were interpolated and indicated as such. Also in this period, there are times when large numbers of gridpoints are missing, particularly over the Asian continent. For more information, see the documentation [https://rda.ucar.edu/datasets/d010000/documentation/] about original data points. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png DSS SLP Grid dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral GRIDDING METHODS MAPS > MAPS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Platforms ESSPO > 433L ESSPO U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Projects EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None grid 5 eng utf-8 climatologyMeteorologyAtmosphere -180.0 180.0 15.0 90.0 1899-01-01T1300+00 2026-04-03T1200+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 145.486 https://gdex.ucar.edu/datasets/d010000/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d010000/dataaccess/ https Data Access Related Link download none asNeeded
