NOTOS IGY Daily Southern Hemisphere Sea-Level Pressure and 500 mb Height Grids for 1957 June to 1958 December

The grids in this dataset contain Southern Hemisphere sea-level pressure and 500 millibar height data for the International Geophysical Year (IGY) period of June 1957 to December 1958. The data are on a 5-degree latitude/longitude grid covering the hemisphere from 15S to the South Pole. The data originally came from South Africa where it was on a 10-degree by 5-degree diamond latitude/longitude grid. DSS interpolated data to the missing gridpoints to provide a resolution of five degrees in both directions.
