The task of generating Coupled Model Intercomparison Project Phase 5 (CMIP5) data from a climate model’s raw output requires considerable human and computing resources beyond the modelling itself. The CMIP5 data generation, checking and publication generally continue for months after the climate model experimentation is complete. The information in this report is specifically aimed at climate data analysts who are seeking a summary of the Australian Community Climate and Earth-System Simulator (ACCESS) CMIP5 model features and their experimental outputs. We summarise the major components that make up the ACCESS climate models, including the principal differences between the ACCESS1.0 and ACCESS1.3 models. We provide contact information for the principal modellers, and a list of recent research papers that describe the ACCESS models in more detail and focus on results from these models. We list the CMIP5 experiments that have been performed to date with the ACCESS models, as well as the branch year for experiments initialised from different time points of the pre-industrial control experiment. A summary of the forcings applied in each experiment is also given. The basic steps of the data generation and publication are described, namely, 1) post-processing from raw to CMIP5 data, 2) quality control of CMIP5 data and 3) the CMIP5 data archive, available at the National Computing and Infrastructure (NCI) National Facility. Both the standard name and the “long name” of every published parameter are tabulated for easy identification. Crucial to reliable and up-to-date analysis are the ACCESS parameter versions, required when a parameter’s definition is updated. This provides analysts with assurance that they are using the latest versions of the ACCESS CMIP5 parameters. At the time of printing, the ACCESS CMIP5 submission includes data for 233 parameters from 7 experiments. The ACCESS submission includes data for most of the core CMIP5 experiments. Most experiments have a single ensemble member, however the number of members is expected to increase especially for the historical and historical “attribution” runs. As an indicator of the success of the CMIP5 data submission described here, at the time of this report’s completion, the ACCESS1.0 and 1.3 output fields have been used respectively in 50 and 31 publications that are based on the CMIP5 data sets.
