tropospheric ozone, ground-level ozone, ground level ozone, low atmospheric ozone, surface ozone
Tropospheric (lower atmospheric) ozone is potentially an important greenhouse gas. Measurements show that tropospheric ozone is increasing in concentration in the Northern Hemisphere (where there is more human influence), perhaps 1% per year, but the situation is not as clear as for other greenhouse gases., ground-level ozone - ozone in the lowermost part of the troposphere
