From the Australian National Meteorological Research Centre, twice daily Southern Hemisphere grids on a polar stereographic projection. DSS derived the monthly mean grids. Later and ongoing data may be available directly from ABM.

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).
