| Zusammenfassung |
| Using coincident observations of total ozone from the Total Ozone Mapping
Spectrometer (TOMS) and stratospheric ozone profiles from the Solar Backscattered
Ultraviolet (SBUV) instruments, detailed maps of tropospheric ozone have been derived
on a daily basis over a time period spanning more than two decades. The resultant
climatological seasonal depictions of the tropospheric ozone residual (TOR) show much
more detail than an earlier analysis that had used coincident TOMS and Stratospheric
Aerosol and Gas Experiment (SAGE) ozone profiles, although there are many similarities
between the TOMS/SAGE TOR and the TOMS/SBUV TOR climatologies. In particular,
both TOR seasonal depictions show large enhancements in the southern tropics and
subtropics in austral spring and at northern temperate latitudes during the summer. The
much greater detail in this new data set clearly defines the regional aspect of tropospheric
ozone pollution in northeastern India, eastern United States, eastern China, and west and
southern Africa. Being able to define monthly climatologies for each year of the data
record provides enough temporal resolution to illustrate significant interannual variability
in some of these regions. |
