| Zusammenfassung |
| Fractional release factors (FRFs) of organic trace gases are
time-independent quantities that influence the calculation of Global Warming
Potentials and Ozone Depletion Potentials. We present the first set of
vertically resolved FRFs for 15 long-lived halocarbons in the tropical
stratosphere up to 34 km altitude. They were calculated from measurements on
air samples collected on board balloons and a high altitude aircraft. We
compare the derived dependencies of FRFs on the mean stratospheric transit
times (the so-called mean ages of air) with similarly derived FRFs
originating from measurements at higher latitudes and find significant
differences. Moreover a comparison with averaged FRFs currently used by the
World Meteorological Organisation revealed the limitations of these measures
due to their observed vertical and latitudinal variability. The presented
data set could be used to improve future ozone level and climate
projections. |
