Zusammenfassung |
Stratospheric O3 and NO2 abundances measured by different
remote sensing instruments are inter-compared: (1) Line-of-sight
absorptions and vertical profiles inferred from solar spectra in
the ultra-violet (UV), visible and infrared (IR) wavelength ranges
measured by the LPMA/DOAS (Limb Profile Monitor of the
Atmosphere/Differential Optical Absorption Spectroscopy) balloon
payload during balloon ascent/descent and solar occultation are
examined with respect to internal consistency. (2) The balloon
borne stratospheric profiles of O3 and NO2 are compared to
collocated space-borne skylight limb observations of the
Envisat/SCIAMACHY satellite instrument. The trace gas profiles
are retrieved from SCIAMACHY spectra using different algorithms
developed at the Universities of Bremen and Heidelberg and at the
Harvard-Smithsonian Center for Astrophysics. A comparison scheme
is used that accounts for the spatial and temporal mismatch as
well as differing photochemical conditions between the balloon and
satellite borne measurements. It is found that the balloon borne
measurements internally agree to within ±10% and
±20% for O3 and NO2, respectively, whereas the
agreement with the satellite is ±20% for both gases in the
20 km to 30 km altitude range and in general worse below 20 km. |
