The Cryogenic Infrared Spectrometers and Telescope for the
Atmosphere – New Frontiers (CRISTA-NF), an airborne infrared
limb-sounder, was operated aboard the high-flying Russian
research aircraft M55-Geophysica during the Arctic RECONCILE
campaign from January to March 2010. This paper describes the
calibration process of the instrument and the
retrieval algorithm employed and then proceeds to present retrieved
trace gas volume mixing ratio cross-sections for one specific flight
in this campaign. We are able to resolve the uppermost
troposphere/lower stratosphere for several trace gas species
for several kilometres below the flight altitude (16 to
19 km) with an unprecedented vertical resolution of 400 to
500 m for the limb-sounding technique. The instrument points sideways
with respect to the flight direction. Therefore, the observations are
also characterised by a rather high horizontal sampling along
the flight track, which provides a full vertical profile every
≈15 km. Assembling the vertical trace gas
profiles derived from CRISTA-NF measurements to cross-sections
shows filaments of vortex and extra-vortex air masses in the
vicinity of the polar vortex.
During this campaign, the M55-Geophysica carried further
instruments enabling trace gas volume mixing
ratios derived from CRISTA-NF to be validated by comparing them with
measurements by the in
situ instruments HAGAR and FOZAN and observations by
MIPAS-STR. This validation suggests that the retrieved trace
gas volume mixing ratios are both qualitatively and quantitatively
reliable. |
