| Zusammenfassung |
| This study describes the retrieval of water vapor vertical distributions in
the upper troposphere and lower stratosphere (UTLS) altitude range from
space-borne observations of the scattered solar light made in limb viewing
geometry. First results using measurements from
SCIAMACHY (Scanning Imaging Absorption spectroMeter for Atmospheric
CHartographY) aboard ENVISAT (Environmental Satellite) are presented here.
In previous publications, the retrieval of water vapor vertical
distributions has been achieved exploiting either the emitted radiance
leaving the atmosphere or the transmitted solar radiation. In this study,
the scattered solar radiation is used as a new source of information on the
water vapor content in the UTLS region.
A recently developed retrieval algorithm utilizes the differential
absorption structure of the water vapor in 1353–1410 nm spectral range and
yields the water vapor content in the 11–25 km altitude range.
In this study, the retrieval algorithm is successfully applied to SCIAMACHY
limb measurements and the resulting water vapor profiles are compared to in
situ balloon-borne observations. The results from both satellite and
balloon-borne instruments are found to agree typically within 10 %. |
