ACCESS Model Experiment Library Developed under NeCTAR CWSLab projects 2012-2014, 2015 Climate and NWP configurations Standard, supported experiments Documented run cases NWP experiments based on APS1 & APS2 configurations Formal user testing and evaluation was conducted in 2014 The Centre for Australian Weather and Climate Research A partnership between CSIRO and the Bureau of Meteorology

NWP Research Versions NWP Research versions are also in use at various times. Presently, there is not an official release strategy for research versions, they vary from application to application, based on scientists projects and collaborations. Some research versions are available in the ACCESS Model Experiment Library, such as NWP configurations for T-AMIP, SCM's. ACCESS versions of Stuart Webster's nested suites and 1.5km ENDGAME configurations are also available.
