Optimal estimation retrieval of aerosol microphysical properties from SAGE~II satellite observations in the volcanically unperturbed lower stratosphere
Optimal estimation aerosol microphysical properties SAGE~II satellite observations lower stratosphere
2010/8/12
Stratospheric aerosol particles under non-volcanic conditions are typically smaller than 0.1 μm. Due to fundamental limitations of the scattering theory in the Rayleigh limit, these tiny particles are...

The transport of very short-lived substances into the tropical upper troposphere and lower stratosphere is investigated by a three-dimensional chemical transport model using archived convective updraf...
Increase of upper troposphere/lower stratosphere wave baroclinicity during the second half of the 20th century
upper troposphere lower stratosphere wave baroclinicity 20th century
2009/12/31
A strengthening of the equatorward temperature gradient in the upper troposphere/lower stratosphere (UTLS), at subtropics and midlatitudes, is consistently reproduced in several modelling studies of t...
