| Summary: | The new Ozone Mapping and Profiler Suite (OMPS), which launched on the
Suomi National Polar-orbiting Partnership satellite in October 2011,
gives a detailed view of the development of the Antarctic ozone hole and
extends the long series of satellite ozone measurements that go back to
the early 1970s. OMPS includes two modules – nadir and limb – to measure
profile and total ozone concentrations. The new limb module is designed
to measure the vertical profile of ozone between the lowermost
stratosphere and the mesosphere. The OMPS observations over Antarctica
show excellent agreement with the measurements obtained from independent
satellite and ground-based instruments. This validation demonstrates
that OMPS data can ably extend the ozone time series over Antarctica in
the future. The OMPS observations are used to monitor and characterize
the evolution of the 2012 Antarctic ozone hole. While large ozone losses
were observed in September 2012, a strong ozone rebound occurred in
October and November 2012. This ozone rebound is characterized by rapid
increases of ozone at mid-stratospheric levels and a splitting of the
ozone hole in early November. The 2012 Antarctic ozone hole was the
second smallest on record since 1988. |
