Studies on distribution and variability of water vapour concentrations on base of remote sensing and in-situ data

Objective

The water vapour plays a major role in the balance of planetary radiation, influences and responds to atmospheric motions and plays a key role in many aspects of atmospheric chemistry. It is emphasized that an increase of water vapour causes a cooling of the lower stratosphere that is comparable to the contribution due to ozone changes. In view of the potential effects on climate change it is important to assess reciprocal relationship between water vapour and climate change. Water vapour measurements have been difficult. In situ ones suffer from water sticking to surfaces, while sharp gradients present difficulties for remote sensing techniques. The analysis of remote sensing data is additionally complicated by a lack of understanding of the fundamental physics behind the observed spectrum. To rise to the task, the researcher proposes to tap both, the remote sensing and in situ data. Satellite data sets enable characterising large-scale variations of water vapour. In situ and ground-based data sets make possible the investigation at smaller spatial scales, for long-term monitoring and for validation of satellite data. Mean distribution of the gas, its seasonal, non-seasonal and long-term variations will be considered including the dependence on macro circulation patterns. The project will allow the researcher an advanced training in the host organisation, especially in satellite data validation.
