Summary
GNSS meteorology is a technique for water vapor estimation from analysis of GNSS signals acqired by GNSS receivers. Some of its outputs have been used in meteorology, mainly in numerical weather prediction models.
The main goal of the project is to evaluate possibilities of GNSS meteorology outputs for meteorological nowcasting, therefore for a short term weather prediction. Nowcasting is important mainly for extreme weather events prediction (storms, gale, etc.). Horizontal tropospheric gradients which represent azimutal assymetry of signal delay in the troposphere will be mainly evaluted in the project. This azimutal assymetry is mainly during the warmer part of the year caused by water vapor. Preliminary scientific works show that horizontal tropospheric gradients might have a good potential for meteorology. As a second step changes of integrated water vapor values will be studied before, during and after selected relevant weather events in an attempt to find potentical indicators helping predict them.
Project will be primarly realized using an existing extensive Benchmark dataset covering four european countries and a period of May and June 2013. This dataset was established within an european project GNSS4SWEC. Moreover, data for selected extreme weather events from the Czech and Slovak Republic will be collected and processed.
Topic of the project is in a full accordance with a disertation thesis topic of the main researcher. The dissertation topic is: Using GNSS meteorology for nowcasting support in meteorology.
