I think we are at cross purposes. You appear to imagine that the ozone level has some relevance to AGW research, and that therefore you are exposing data manipulation on this subject.

The reason people measure ozone levels is that artificially generated ozone is a polutant. It causes sometimes life threatening asthma in susceptible people, and for this reason it is important for those at risk to know when the level is dangerously high. Therefore it is measured at locations where it may become high, because that is where the danger lies.

These measurements are supremely irrelevant to any aspect of global climate research. As Thorne noted, you may perhaps be confused by the tendency of anti-environmentalists to conflate the current concern over CO2 with the 1980s concern over ozone depeletion. The two are entirely separate issues. (Well, almost. A serious increase in ozone depletion might conceivably add to incoming solar radiation enough to have an impact on climate, but the contingency is happily remote, since we seem to have successfully limited the release of ozone depleting pollutants.) In any case, the previous concern was over loss of ozone, so environmental fraudsters would hardly be trying to exagerate the levels, leaving aside that they would be taking measurements several hundred feet too low if that were the object.

All this you could have discovered for yourself with five minutes on Google, so why do we have to keep educating you in the basics?
