Climate and Weather Science Laboratory

The Climate and Weather Science Laboratory (CWSlab) provides a national platform for researchers and government agencies to simulate, analyse and predict climate and weather phenomena.

It is an Australian Government NeCTAR-funded project led by the Bureau of Meteorology, involving NCI, CSIRO and the ARC Centre of Excellence for Climate System Science.

CWSlab is as a portal where researchers from different institutions can share model source code, experiments and data in a fully supported environment.

NCI’s integrated cloud, supercomputing and data storage infrastructure provides the perfect hosting platform for all the key ingredients necessary to develop and perform climate and weather simulations and create an accessible archive of climate and weather data for analysis.

Working closely with end-users, NCI has integrated and enhanced the following software to form CWSlab:

  • the Australian Community Climate and Earth System Simulator (ACCESS) — Australia’s national, state-of-the-art weather and climate simulation and prediction software  from the Centre for Australian Weather and Climate Research (CAWCR), a joint research centre of CSIRO and the Bureau of Meteorology.
  •  Earth System Grid software: the product of an international collaboration to provide data federation, secure access and search-ability for climate model data from the World Climate Research Programme and the United Nations Intergovernmental Panel on Climate Change (IPCC).

The CWSlab portal also provides an interface for several data analysis tools, including UV‐CDAT (Ultra‐scale Visualization Climate Data Analysis Tools, of which NCI is a development partner) and the CDX (Climate Data Exchange) toolkit. CWS also integrates NCI’s Drishti visualisation software.
