Gridded average wind velocity metadata


Title Average monthly wind velocity grids (2004-2008)


Custodian Bureau of Meteorology
Jurisdiction Australia


Abstract Average monthly wind velocity grids.
The grids show the wind speed and direction values across Australia.
The mean data are based on the period 1st January 2004 - 31st December 2008.

Data Quality

Lineage Gridded data were generated by the MesoLAPS_PT125 Numerical Weather Prediction (NWP) dynamical model which is operated by the Bureau of Meteorology. The resolution of the data are 0.125 degrees (approximately 12.5 km).
The models 10 metre zonal (u) and meridional (v) wind components at 00 UTC was used in deriving the grids.
The NWP model is used to provide operational guidance in weather forecasting. The LAPS PT375 model performs the assimilation and analysis, which is then interpolated to 0.125 degrees resolution. The model performs its own forecast.
NetCDF files describe their content using three types of metadata:
  • Dimensions, which define the size of the different variables.
  • Variables, which specify the type of data the file contains.
  • Global attributes, which provide additional information that applies to all the data in the file.
The variables consist of the coordinates in space and time plus the physical field itself. Other variables with additional information may also be included.
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.
Attribute Accuracy Not applicable
Logical Consistency Not applicable
Completeness No missing data
