|Title||Average monthly and annual mean sea level pressure grids (1979-2000)|
|Custodian||Bureau of Meteorology|
|Abstract||Average monthly and average annual mean sea level pressure grids.
The grids show the mean sea level pressure values across Australia.
The mean data are based on the period 1979 - 2000.

|Lineage||The climatology used is based on the United States of America's National Centers for Environmental Prediction NCEP2 re-analyses for the period 1979-2000.
The reanalysis is done at NCEP (formerly NMC) using T62 (209 km) global spectral model of 28 vertical levels. This is the same model used in the assimilation system, as implemented in the NCEP operational system in December 1994.
The model has 5 levels in the boundary layer and about 7 levels above 100 hPa. The lowest model level is about 5 hPa from the surface, and the top level is at about 3 hPa.
The resolution of the original global spectral model is 2.5 degrees and the Australian grids were created by re-sampling the original grid from 2.5 degrees down to 1.25 degrees.
|Positional Accuracy||Various types of data are used as part of the assimilation process in the model. These include synoptic, metar, ship, buoys and sonde as well as satellite driven observations. These observational data generally have an associated accuracy within the model resolution.|
