| ozone |
is found in two places, in the upper atmosphere and at ground level. It is the upper level of ozone that acts as a greenhouse gas -- this ozone occurs naturally. Man-made ozone is found at ground level, and is a byproduct of burning fossil fuels (CO reacts with N 2 O and sunlight to produce O 3 ). Ground level ozone is too short-lived to be a greenhouse gas, but it is a siginificant toxic air pollutant.
