Reaching the lower stratosphere: validating an extended vertical grid for COSMO
COSMO validating
2015/8/6
This study presents an extended vertical grid for
the regional atmospheric model COSMO (COnsortium for
Small-scale MOdeling) reaching up to 33 km. The extended
setup has been used to stably simulat...

The Michelson Interferometer for Passive Atmospheric Sounding onboard ENVISAT (MIPAS–E) offers the opportunity to detect and spectrally resolve many atmospheric minor constituents affecting atmospheri...
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...

Temperature data from the COSMIC GPS-RO satellite constellation are used to study the distribution and variability of planetary wave activity in the low to mid- stratosphere (15–40 km) of the Arctic a...
Modeling the transport of very short-lived substances into the tropical upper troposphere and lower stratosphere
very short-lived substances tropical upper troposphere lower stratosphere
2009/12/31
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...
What drives the observed variability of HCN in the troposphere and lower stratosphere?
