Offer Description
The Czech Technical University in Prague (CTU), Department of Hydraulics and Hydrology, invites applications for a PhD position within the international project Reconstructing 4D tropospheric water vapour distribution by combining observations from GNSS receivers and commercial microwave links (TROTOMO). The project investigates uncertainties in water vapor estimates from E-band commercial microwave links (CML) and GNSS receivers, and integrates both into local and regional tomographic models to improve urban-scale weather analysis and forecasting. The position offers close collaboration with Dr. Jan Kaplon (Wrocław University of Environmental and Life Sciences) and Dr. Estera Trzcina and Prof. Witold Rohm (University of Wrocław), including short-term research stays in Poland.
Goals and Objectives:
The candidate will lead the quantification and refinement of CML water vapor estimates, with strong involvement in data collection and cross-technique analysis. Key tasks include:
- Set up and maintain reference station instrumentation for the dedicated CML experiment; collaborate with Polish partners on UAV and GNSS field surveys and analyze the combined dataset
- Assess sources of uncertainty in CML water vapor retrieval against reference station, GNSS, and UAV profiling data
- Develop an uncertainty estimation model for CML retrieval suitable for sparse-reference-data conditions
- Investigate, with Polish partners, how differing error structures of CML and GNSS water vapor estimates can be exploited to reduce observation errors in both
- Validate the proposed approaches on city-scale and regional CML/GNSS datasets
- Contribute to assessing the effect of CML integration on the 4D water vapor field from tomographic reconstruction
