What: 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.
When: November 16-18, 13:00-15:00 UTC each day
Where: Held globally in virtual format.
Free Registration: Please register here before Friday, November 5th, 2021, 23:59 UTC.
Agenda: Coming soon
As of February 2020, TOAR (Tropospheric Ozone Assessment Report: Global metrics for climate change, human health and crop/ecosystem research) has entered its second phase (TOAR-II), the first phase having been completed in 2019. The TOAR mission continues, with TOAR-II providing updated and extended information on tropospheric ozone.
Specifically, the goals of TOAR-II are:
- TOAR Ozone Data Portal: Update the ozone observations in the TOAR surface ozone database to include all recent observations (since 2014), and include data from new sites and regions, as well as ozone precursor and meteorological data. Develop methods for including historical data (pre-1975) and create working links to repositories of free tropospheric observations.
- TOAR publications: Exploit the new observational datasets collected by Goal 1 (with data through 2020) to provide an updated state of the science estimate of ozone’s global distribution and trends relevant to climate, human health and vegetation. Extend the statistical toolbox and metrics of the TOAR trend analyses. These results will be published in the open-access, peer-reviewed literature.
- Involve scientists from the atmospheric sciences community, as well as statisticians and scientists who focus on broader issues of global change and sustainability, to identify outstanding science questions in relation to tropospheric ozone. The range of topics can be expanded beyond the scope of the original TOAR effort to investigate the impacts of tropospheric ozone on climate, human health and vegetation, and to address urban-scale issues in addition to the regional and global scale.
- Maximize exploitation of the TOAR Surface Ozone Database by, 1) helping scientists around the world, beyond the TOAR effort, to apply the database to new analyses, and 2) exploring new data science methods to improve the analysis of global ozone trends and their attribution.

The TOAR-II Kick-Off Workshop was held in virtual format over four days in late January and early February 2021. TOAR-II Kick-Off was the first TOAR-II workshop, designed to gather the community and develop the working groups that will produce the papers for the TOAR-II Community Special Issue (the first step of the second Tropospheric Ozone Assessment Report), as well as identify new datasets for the assessment of tropospheric ozone and its impact on climate, health and vegetation.
Details of the workshop are available in a summary pdf, and additional workshop materials (including all presentations) are available on the TOAR-Repository. To get involved, please follow the respective links in the summary pdf.
Further information about TOAR-II can be found in the presentation slides from the on-line Quickstart Event held on September 16, 2020:
