Congratulations to our colleague, Pavol Nechaj, on successfully completing his external PhD studies in Environmental Physics and Meteorology at the Faculty of Mathematics, Physics and Informatics, Comenius University in Bratislava.
His research focused on the detection of low-level wind shear using Doppler lidar data - a meteorological phenomenon that can significantly affect aircraft safety during take-off and landing.
The work was closely connected with the MicroStep-MIS project APVV-15-0663, “A Novel Method for Low Level Wind Shear Alert Calculation from Data Measured by Lidar.” Using data from the Doppler lidar operated at M. R. Štefánik Airport in Bratislava, he developed a new algorithm for low-level wind shear detection in line with ICAO recommendations.
The algorithm analyzes individual lidar beams from PPI scans and applies a dynamically changing detection window, providing additional information about the spatial consistency of detected events. It was validated on real cases from the complex environment of Bratislava Airport and compared with pilot reports over a 5.5-year period.
We are proud that this research has already found its way into practice: the algorithm is now used in the MicroStep-MIS IMS LLWAS system. For our colleague, the PhD offered a valuable opportunity to combine academic research with real operational data, advanced technology, and practical aviation meteorology requirements. For MicroStep-MIS, it brought scientifically validated knowledge directly into product development and strengthened our long-term focus on innovation in meteorological systems.
The research was also supported by valuable cooperation with the Slovak Hydrometeorological Institute, which provided data and shared operational experience from meteorological practice.
This achievement is a strong example of why cooperation between research, industry, and operational services is so important. It turns scientific ideas into practical solutions that can support safer and more informed decision-making. Congratulations on this well-deserved milestone!
