This dataset contains 500mb heights for the Southern Hemisphere for the period June 1968 to August 1977. The grid has a resolution of 10 degrees in the longitudinal direction and 5 degrees in the latitudinal direction and covers the hemisphere from 15S to the South Pole.

The data were received from the Australian Numerical Meteorology Research Centre.

Unless you have a special interest in this dataset, DSS recommends that you use one of our reanalysis datasets, such as ds090.0. That's because those are based on a more complete collection of observations, improved analysis methods, and are provided in a common modern format (GRIB).
