-The ATLAS Collaboration is releasing a new set of proton-proton collision data to the public for educational purposes. The data has been collected by the ATLAS detector at the Large Hadron Collider during the year 2016 and corresponds to an integrated luminosity of 10 fb $$^{−1}$$. This dataset is accompanied by simulated events describing both several Standard Model processes, as well as hypothetical Beyond Standard Model (SM) signal production. Associated computing tools are provided to make the analysis of the dataset easily accessible. This document summarises the properties of the 13 TeV ATLAS Open Data set.  The general aim of the dataset and tools released is to provide user-friendly and straightforward interactive interfaces to replicate the procedures used by high-energy-physics researchers and enable users to experience the analysis of particle-physics data in educational environments.
