The second phase of the Tropospheric Ozone Assessment Report (TOAR-II) is well underway with activities guided by fourteen Focus Working Groups. We are now inviting the TOAR community to attend the TOAR-II Manuscript Scoping Event, a 3-day workshop to identify the papers that will be submitted to the TOAR-II Community Special Issue by September 2023. This will be an interactive event with several breakout sessions to build collaboration across the fourteen Working Groups.
