| Zusammenfassung |
| The Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere – New
Frontiers (CRISTA-NF) instrument participated in the
AMMA-SCOUT-O3 measurement campaign in July and August 2006. The instrument is
mounted on the high-flying Russian research aircraft M55-Geophysica and
measures limb-emissions in the mid-infrared region in the tangent altitude range of
about 6 to 21 km. We present a new retrieval setup which is based on 9 integrated spectral
windows allowing to retrieve an extended set of trace gases and temperature
fields with high vertical resolution (up to 500 m). Retrieval results are shown for
temperature, water vapor (H2O), ozone (O3), nitric acid (HNO3),
peroxyacetyl nitrate (PAN), carbon tetrachloride (CCl4), and
aerosol extinction.
Comparisons of temperature, O3, and H2O
observations with corresponding in situ measurements on-board M55-Geophysica
show reasonable agreement. In particular, CRISTA-NF observations in the
vicinity of the aircraft resemble horizontal variations found in the in situ
measurements better than corresponding ECMWF fields. |
