The daily and monthly climate variables contained herein have been generated using ANUClimate 1.0 (though ANUClimate 1.1 data is available for most daily products). This is a spatial model, developed by Michael Hutchinson, that integrates a new approach to the interpolation of Australia’s national point climate data to produce climate variables on a 0.01° longitude/latitude grid. Most climate values have been modelled by expressing each value as a normalised anomaly with respect to the gridded 1976-2005 mean. These means and anomalies were all interpolated by trivariate thin plate smoothing spline functions of longitude, latitude and vertically exaggerated elevation using ANUSPLIN Version 4.5, with additional dependences on proximity to the coast for the temperature and vapour pressure variables. Station elevations for the gridded temperature and vapour pressure variables were obtained from 0.01° local averages of grid values from the GEODATA 9 second DEM version 3. Station elevations for the gridded rainfall and pan evaporation variables were obtained from 0.05° local averages of grid values from the GEODATA 9 second DEM version 3.
