      abstract     = {The new remote sensing experiment CRISTA-NF (Cryogenic
                      Infrared Spectrometers and Telescopes for the Atmosphere -
                      New Frontiers) successfully participated in the SCOUT-O3
                      Tropical Aircraft Campaign in November and December 2005.
                      CRISTA-NF operated aboard the high-altitude research
                      aircraft M-55 Geophysica. Mid-infrared spectra (4-15 mu m)
                      were measured in the limb sounding geometry with high
                      spatial resolution (250 m vertical sampling, 5-15 km along
                      track sampling). Measurements were carried out during
                      transfer flights between Oberpfaffenhofen, Germany, and
                      Darwin, Australia, as well as during several local flights
                      near Darwin. Water vapor volume mixing ratios in the upper
                      troposphere and lower stratosphere were derived from the
                      CRISTA-NF radiance measurements by utilizing a rapid
                      radiative transfer forward model and the optimal estimation
                      retrieval approach. CRISTA-NF water vapor measurements below
                      the hygropause have a total retrieval error of $15-40\%$
                      (i.e. root mean square of accuracy and precision). The
                      systematic terms are dominating in the retrieval error
                      budget. The contributions of a priori information to the
                      retrieval results are less than $5-10\%.$ The vertical
                      resolution of the observations is about 250-500 in when
                      permitted by instrument sampling. In this paper we present
                      first results for three transfer flights of the campaign.
                      Being generally in good agreement with corresponding ECMWF
                      operational analyzes, the CRISTA-NF measurements show
                      significantly higher variability and local structures in the
                      upper tropospheric water vapor distributions. (C) 2008
