The phrase "average surface ozone" is correct and usable in written English.
It can be used in scientific or environmental contexts when discussing the typical concentration of ozone at the Earth's surface.
Example: "The study measured the average surface ozone levels over a three-month period to assess air quality."
Alternatives: "mean surface ozone" or "typical surface ozone".
This file contains data and code for the figures in the paper "Average versus high surface ozone levels over the continental U.S.A.: Model bias, background influences, and interannual variability". Article abstract: U.S. background ozone (O3) includes O3 produced from anthropogenic O3 precursors emitted outside of the U.S.A., from global methane, and from any natural sources.
We estimate that these measures could reduce global population-weighted average surface PM2.5 and ozone concentrations by 3.98 4.92 µg/m (23.0 33.7%) and 4.71 11.0 ppb (6.5 17.0%), respectively, and avoid 0.6 4.4 and 0.04 0.52 million annual premature deaths globally in 2030.
Results: We estimated that, for PM2.5 and ozone, respectively, fully implementing these measures could reduce global population-weighted average surface concentrations by 23 34% and 7 17% and avoid 0.6 4.4 and 0.04 0.52 million annual premature deaths globally in 2030.
