abstract = {[1] Vertical profiles of water vapor concentration at high
latitudes (57-72 degreesN; 64-89 degreesS) were observed by
the Improved Limb Atmospheric Spectrometer (ILAS) solar
occultation sensor aboard the Advanced Earth Observing
Satellite (ADEOS). These measurements were made continuously
from November 1996 through June 1997 with some additional
periods in September to October 1996. A validation study of
the water vapor data processed with the version 5.20 ILAS
retrieval algorithm is presented in this paper. Uncertainty
and general characteristics of the ILAS water vapor
measurements are briefly reviewed. Comparisons are made with
data obtained by (1) the ILAS validation balloon campaigns
at Kiruna, Sweden and at Fairbanks, Alaska; (2) the aircraft
measurements under the Photochemistry of Ozone Loss in the
Arctic Region in Summer (POLARIS) campaign; and (3)
available satellite measurements of the version 19 Halogen
Occultation Experiment (HALOE) and the version 6
Stratospheric Aerosol and Gas Experiment II (SAGE II). The
agreement between ILAS water vapor and all independent
reliable correlative measurements in the altitude region of
15-60 km is better than $10\%$ for the majority of cases and
better than $20\%$ for all comparisons, with the exception
of some isolated cases detailed in this paper.
Climatological comparisons of ILAS data with Upper
Atmosphere Research Satellite (UARS) climatology and HALOE
data show the overall consistency of ILAS water vapor data
considering the known features of atmospheric circulation.
The characteristics of ILAS measurements, i.e., high
sampling frequency in polar latitudes with high vertical
resolution along with the good data quality, make the ILAS
water vapor data set valuable for various polar
stratospheric research applications.},
