Evidence of transport, sedimentation and coagulation mechanisms in the relaxation of post-volcanic stratospheric aerosols
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 a...

| description | 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.<br><br><b>Key words. </b>Atmospheric composition
