Integrated Remote Sensing
We develop and apply novel observation techniques to better understand the processes determining the atmospheric water cycle. Observations and process knowledge are used to evaluate and drive models in order to arrive at better weather forecasts and climate predictions.
Topical Research Areas:
- Atmospheric boundary layer
- Cloud processes
- Arctic Amplification
- Energy meteorology
- Observational networks of the future
Methodological Research Areas:
- Microwave remote sensing
- Radiative transfer simulations
- Atmospheric retrieval algorithm development
- Reanalysis
