| Zusammenfassung |
| Vertical profiles of stratospheric bromine monoxide (BrO) retrieved daily
from ENVISAT/SCIAMACHY (ENVIronmental SATellite/SCanning Imaging Absorption
spectroMeter for Atmospheric CHartographY) limb scatter data and from
ground-based UV-visible observations performed at Harestua (60° N, 11° E),
Observatoire de Haute-Provence (44° N, 5.5° E), and Lauder (45° S,
170° E) are compared in the 15–27 km altitude range for the 2002–2006,
2005–2006, and 2002–2005 periods, respectively. At the three stations, the SCIAMACHY and ground-based
UV-visible mean profiles agree reasonably well, with relative difference smaller
than 23%. When comparing the BrO partial columns, the
agreement obtained is good, with mean relative differences smaller than
11% and corresponding standard deviations in the 13–19% range. These comparison results are obtained, however, using different
BrO cross sections in SCIAMACHY limb and ground-based UV-visible retrievals. The
seasonal variation of the BrO columns at the three stations is consistently
captured by both retrievals as well as large BrO column events occurring
during the winter and early spring at Harestua which are associated with
bromine activation. |
