Human activity has damaged this protective layer of the stratosphere, but scientists say the ozone layer is on track for recovery.
(However, we only recommend the use of a subset of these series for long-term trend analysis.) The re-evaluated data sets are believed to be particularly useful to compare long-term ozone variability with anthropogenic forcings of the ozone layer (such as anthropogenic ozone depletion, its ...

Observing the world‐wide concentration and distribution of ozone is important for monitoring the evolution of the ozone layer, to derive the amount of UV, to provide ozone and UV forecasts and to improve weather forecasting. Monitoring ozone is the primary function of the Global Ozone Monitoring ...
