U.S. Navy Northern Hemisphere Daily (and Monthly) Sea-Level Pressure and 500 Millibar Height Grids for 1946Jan to 1993Dec

The gridded daily sea-level pressure analyses in this dataset were produced by the operational models of the U.S. Navy Fleet Numerical Oceanography Center (FNOC). The data are arranged in a 63-by-63 polar-stereographic grid covering the Northern Hemisphere for the period January 1946 to December 1993. DSS has produced a set of monthly grids from the dailies.

This dataset also includes daily 500 millibar geopotential height grids for the period January 1946 to December 1955 on the same polar-stereographic grid as the sea-level pressure data.

本数据集之网格化每日海平面气压分析由美国海军舰队数值海洋学中心（FNOC）的运行模型所生成。数据以63x63的极地立体网格排列，覆盖北半球，时间跨度为1946年1月至1993年12月。数据服务系统（DSS）已从每日数据中生成了一套月度网格。此外，该数据集还包含了同一直角网格上，1946年1月至1955年12月期间的每日500百帕位势高度网格。
