abstract = {The Gimballed Limb Observer for Radiance Imaging of the
Atmosphere (GLORIA) is an airborne infrared limb imager
combining a two-dimensional infrared detector with a Fourier
transform spectrometer. It was operated aboard the new
German Gulfstream G550 High Altitude LOng Range (HALO)
research aircraft during the Transport And Composition in
the upper Troposphere/lowermost Stratosphere (TACTS) and
Earth System Model Validation (ESMVAL) campaigns in summer
2012.This paper describes the retrieval of temperature and
trace gas (H2O, O3, HNO3) volume mixing ratios from GLORIA
dynamics mode spectra that are spectrally sampled every
0.625 cm−1. A total of 26 integrated spectral windows are
employed in a joint fit to retrieve seven targets using
consecutively a fast and an accurate tabulated radiative
transfer model. Typical diagnostic quantities are provided
including effects of uncertainties in the calibration and
horizontal resolution along the line of sight. Simultaneous
in situ observations by the Basic Halo Measurement and
Sensor System (BAHAMAS), the Fast In-situ Stratospheric
Hygrometer (FISH), an ozone detector named Fairo, and the
Atmospheric chemical Ionization Mass Spectrometer (AIMS)
allow a validation of retrieved values for three flights in
the upper troposphere/lowermost stratosphere region spanning
polar and sub-tropical latitudes. A high correlation is
achieved between the remote sensing and the in situ trace
gas data, and discrepancies can to a large extent be
attributed to differences in the probed air masses caused by
different sampling characteristics of the instruments.This
1-D processing of GLORIA dynamics mode spectra provides the
basis for future tomographic inversions from circular and
linear flight paths to better understand selected dynamical
processes of the upper troposphere and lowermost
stratosphere.},
