| Zusammenfassung |
Spatio-temporal
distributions of stratospheric aerosols, measured by the ORA instrument from
August 1992 until May 1993, are presented in the latitude range (40° S–40°
N). Particle total number density, mode radius and distribution width are
derived and interpreted. The respective roles of advection, sedimentation and
coagulation are discussed. We also identify clear transport/sedimentation
patterns and we show the enhancement of coagulation in stagnation regions.
Efficient transport of aerosol particles up to 50 km is suggested.
