Mapping tropospheric ozone profiles from an airborne ultraviolet-visible spectrometer.
We present a novel technique for retrieving ozone (O3) profiles and especially tropospheric O3 from airborne UV/visible spectrometer measurements. This technique utilizes radiance spectra from one down-looking and two up-looking (85 degrees and 75 degrees) directions, taking advantage of the O3 absorption structure in the Huggins (300-340-nm) and Chappuis (530-650-nm) bands. This technique is e...
متن کاملTropospheric ozone.
Background: Tropospheric ozone is difficult to retrieve from satellites because of the abundance of ozone in the stratosphere. Tropospheric ozone has become a significant environmental issue and can be exacerbated by UT/LS folding and longrange transport events. Ozone can be moved from the stratosphere to the troposphere by upper tropospheric meteorological events. The Ozone Monitoring Instrume...

متن کاملThe tropospheric ozone problem.
Derived from measurements it has been concluded that in the last hundred years the ground-based ozone concentration has risen by about a factor of two. Models also show a doubling of the tropospheric ozone content due to human activities. It is very likely that mean ozone concentration will further increase. In contrast, episodes with excess ozone levels ("summer smog") have become rare in Cent...
