As of February 2020, TOAR has entered its second phase (TOAR-II), the first phase having been completed in 2019. The TOAR mission continues, but TOAR-II will provide 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 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 the broad range of scientists from Goal 3 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.
