TOAR (Tropospheric Ozone Assessment Report)

TOAR is a science effort initiated by IGAC, and developed by an international team of experts. TOAR receives financial and logistical support from IGAC, the US National Oceanic and Atmospheric Administration, and the World Meteorological Organization. The main goals of this community are:

  1. Produce the first tropospheric ozone assessment report based on the peer-reviewed literature and new analyses.

  2. Generate easily accessible, documented data on ozone exposure and dose metrics at hundreds of measurement sites around the world, freely accessible for research on the global-scale impact of ozone on climate, human health and crop/ecosystem productivity.


Papers published so far:

  1. Schultz et al. (2017): Tropospheric Ozone Assessment Report: Database and metrics data of global surface ozone observations, doi: 10. 1525/elementa.244.

  2. Chang et al. (2017): Regional trend analysis of surface ozone observations from monitoring networks in eastern North America, Europe and Esat Asia, doi: 10. 1525/elementa.243.
