24 months Postdoc / Scientist position in the field of mid-IR laser absorption spectroscopy
Empa
Dübendorf, CH
vor 2 Tg.

The project is aimed at the further development and intensive field application of a high-precision, miniaturized mid-IR spectrometer based on quantum cascade lasers (QCLs) for water vapor measurements in the upper atmosphere (UTLS) aboard meteorological balloons.

The final goal is to establish this technique as an alternative to cryogenic frost point hygrometry. The activities are supported by GCOS and involve intense collaboration with MeteoSwiss, METAS and the GRUAN station in Lindenberg.

The project forsees multiple atmospheric flights up to the stratosphere and consecutive data analysis and interpretation.

Participation at international intercomparison campaign is also planed.
