The Tropospheric Ozone Assessment Report (TOAR) is an initiative of the International Global Atmospheric Chemistry (IGAC) project. TOAR-II is the second phase of TOAR. It builds on the successful completion of the first comprehensive assessment on tropospheric ozone and will last from 2020 to 2024. The TOAR-II Data User Workshop 2022 introduced the new TOAR database and its tools for accessing and analysing TOAR data. This publication contains all lectures that were held during the on-site event. Furthermore, users' workflows and data analysis problems have been tackled in hands-on sessions. The feedback from this workshop will also influence the further development of the TOAR infrastructure. All workshop material including the hands-on codes can be found at https://gitlab.jsc.fz-juelich.de/esde/toar-public/toar-data-user-workshop-2022.
