Australia’s Environment Explorer: data description and download

National-scale, comprehensive information on the condition and trajectory of our environment.

 

Disclaimer

Australia’s Environment Explorer is made possible through open data sharing by CSIRO, Bureau of Meteorology, Geoscience Australia, TERN AusCover, ECMWF, NASA and Google. The material provided through this website is experimental and derived through active research. The Australian National University does not have a legislated role in providing authoritative information. All information is made available on the understanding that it does not constitute professional advice. Before relying on the material in any important matter, users should carefully evaluate its accuracy, currency, completeness and relevance for their purposes, and should obtain any appropriate professional advice relevant to their particular circumstances. Links to other websites do not constitute an endorsement of material at those sites, or any associated organisation, product or service.

Data access and format

All gridded data can be accessed and downloaded via NCI’s THREDDS service in NetCDF4 format. If you are familiar with these then you can directly access our data catalogue. You can find annual files with data at the highest temporal and spatial time step available. To access the gridded annual maps you can also follow the Direct Download Links below. If you are not familiar with the NCI THREDDS you can find a good description here. Various software packages have native or external utilities to read NetCDF format, including QGIS, ArcGIS (instructions here), Matlab, Python, and ENVI/IDL. You can find a partial (if somewhat dated) list of processing and viewing software here.
