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. A data-gathering event was organized via Zoom on January 21st, 2022 to inform the scientific community about the plans for TOAR-II and how to contribute data to the TOAR data portal and the TOAR database. This publication contains all presentation files from this event together with the video and audio recording, as well as transcripts of the question and answer sessions.
