| Zusammenfassung |
| The Gimballed Limb Observer for Radiance Imaging in the Atmosphere
(GLORIA) is a new remote sensing instrument combining a Fourier
transform infrared spectrometer with a highly flexible gimbal
mount. The 2-D detector array measures spectra with a uniquely spatial
and spectral resolution. Air masses can be observed from different
directions by turning the instrument's line of sight in the gimbal
frame.
During December 2011 the instrument flew for the first time on the
high flying Russian Geophysica M-55 research plane over Kiruna
(Sweden). At that time, there was a very strong and cold polar vortex
with several filamentary structures at its boundary and within the
operation radius of the aircraft. We retrieved fields of temperature
and several important trace gases from measurements obtained during
the ESSenCe campaign and compared them to 3-D model calculations of
the atmosphere.
We show that there exists filamentary structure of less than 1 km
vertical extent, which is only visible due to the high vertical
resolution of 300 m provided by GLORIA and is not fully resolved in
the comparison data. |
