ERA5 Visualiser is an interactive desktop application for the analysis and visualisation of ERA5 reanalysis data sets, including the Bureau of Meteorology tropical cyclone database. Hourly MSL Pressure and Total Cloud Cover data covering Australia at 0.25 degree resolution from the last 83 years (1940-2022) have been downloaded from the ERA5 hourly data on single levels from 1940 to present dataset as netCDF files. The tropical cyclone database has been downloaded as a CSV file.

The ERA5 Visualiser application is written entirely in IDL.

Climate Visualiser is an interactive desktop application for the analysis and visualisation of AGCD and ANUClimate data sets. Monthly gridded maximum and minimum temperature data at 0.05 degree resolution, and rainfall data at 0.01 and 0.05 degree resolution, over Australia from 1900-2022 (AGCD), and at 0.01 degree resolution from 1960-2021 (ANUClimate), have been downloaded from the NCI (National Computational Infrastructure) OPeNDAP server as netCDF files.

The Climate Visualiser application is written entirely in IDL.

Map Background is an interactive desktop application used to create background images for the web utilising coastline, elevation and location spatial data sets. Features include simple updating of the map backgrounds with interactive placement of location name labels, and automatic generation of hotlinks for clickable maps.

The Map Background application is written entirely in IDL.
