Algorithms for the inversion of lidar signals: Rayleigh-Mie measurements in the stratosphere
lidar dial ozone aerosol temperature
2015/10/8
We report the features and the performances of the algorithms, developed at the Lidar Station of L'Aquila, for retrieving atmospheric parameters and constituents from elastic lidar signals. The algori...
Could we find any signal of the stratosphere-ionosphere coupling in Antarctica?
ionosphere-stratosphere interaction temperature profiles
2015/9/25
An investigation searching for a possible coupling between the lower ionosphere and the middle atmosphere in Antarctica is here performed on the basis of stratospheric vertical temperature profiles an...
On the cryogenic removal of NOy from the Antarctic polar stratosphere
polar stratosphere reactive nitrogen heterogeneous chemistry tracer-tracer correlations
2015/9/16
We review current knowledge about the annual cycle of transport of nitrogen oxides to, and removal from, the
polar stratosphere, with particular attention to Antarctica where the annual winter denitr...
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...
Tropical troposphere to stratosphere transport of carbon monoxide and long-lived trace species in the Chemical Lagrangian Model of the Stratosphere (CLaMS)
Tropical troposphere long-lived
2014/12/19
Variations in the mixing ratio of trace gases of tropospheric origin entering the stratosphere in the tropics are of interest for assessing both troposphere to stratosphere transport fluxes in the tro...
The use of IASI data to identify systematic errors in the ECMWF forecasts of temperature in the upper stratosphere
IASI data systematic errors the ECMWF temperature the upper stratosphere
2011/2/25
Since data from the Infrared Atmospheric Sounding Interferometer (IASI) became available in 2007, a number of papers have appeared in the literature which have reported relatively large discrepancies ...
Residual circulation trajectories and transit times into the extratropical lowermost stratosphere
the extratropical lowermost stratosphere residual circulation trajectories
2011/2/24
Transport into the extratropical lowermost stratosphere (LMS) can be divided into a slow part (time-scale of several months to years) associated with the global-scale stratospheric residual circulatio...
Analysis of SAGE II ozone of the middle and upper stratosphere for its response to a decadal-scale forcing
SAGE II ozone the middle and upper stratosphere a decadal-scale forcing
2010/12/28
Stratospheric Aerosol and Gas Experiment (SAGE II) Version 6.2 ozone profiles are analyzed for their decadal-scale responses in the middle and upper stratosphere from September 1991 to August 2005. Th...

2010/9/21
The project CARIBIC (http://caribic-atmospheric.com) aims to study atmospheric chemistry and transport by regularly measuring many compounds in the free troposphere and the upper troposphere/lowermost...
Seasonality of Peroxyacetyl nitrate (PAN) in the upper troposphere and lower stratosphere using the MIPAS-E instrument
Peroxyacetyl nitrate the upper troposphere and lower stratosphere the MIPAS-E instrument
2010/8/16
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...
Study on the impact of sudden stratosphere warming in the upper mesosphere-lower thermosphere regions using satellite and HF radar measurements
sudden stratosphere warming the upper mesosphere-lower thermosphere regions satellite and HF radar measurements
2010/8/12
The occurrence of a sudden stratospheric warming (SSW) excites disturbances in the mesosphere-lower thermospheric (MLT) wind and temperature. Here, we have examined the high frequency (HF) radar wind ...
