| Zusammenfassung |
| The upper troposphere and lower stratosphere (UTLS) is a region of special
interest for a variety of dynamical and chemical processes.
Water vapor in the UTLS plays an important role for the radiative budget of the atmosphere, therefore consistent long term measurements are important.
Measurements of scattered sunlight from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartograpY (SCIAMACHY) in the limb viewing geometry
allow to retrieve water vapor in the UTLS, at about 12 to 23 km altitude.
Onboard Envisat, SCIAMACHY measurements are available for nearly one decade, between August 2002 and April 2012.
Here, we present a validation of the latest data version of water vapor from
SCIAMACHY measurements by comparsisons with occultation data from SCIAMACHY, other satellite data and frost point hygrometer data. The time series from 2002 to 2012 is
presented and their variability during the last decade is investigated |
