The use of Global Navigation Satellite Systems (GNSS, e.g. GPS, Galileoetc.) has become an everyday tool for determining our position onearth and in space. GNSS also allow measuring the atmospheric watervapor which is the most important gas for weather prediction andgreenhouse effect. In the TRYAT-project we create learning materialson how to apply the satellite signal to the sensing of atmosphericwater vapor and how to make use of this technique. We want to empowervocational education and training (VET) learners in the fields ofphysics, electronics, electrical engineering, geo- and environmentalengineering and IT. Therefore, we have developed a transnationalpartnership in order to promote science and innovation. In our project we use three GNSS stations which have been installed onthe roofs of VET centers in France, Italy, and Germany. We let VETlearners analyze data from GNSS networks worldwide which arecollected and processed by the German Research Centre for Geosciences(GFZ), University of Naples and Istituto Nazionale di Geofisica eVulcanologia (INGV). We explain vividly and clearly how to calculatethe wet component of the atmospheric delay from GNSS andmeteorological measurements, and why it is important to compute theamount of the precipitable water vapor and to study its influence onweather and climate. We also motivate VET learners to use their smartphone and low-costelectronic to enhance their digital competence and improve the skillsfor experiments in physics and competencies in informatics andelectrical engineering. They confront the high-end professional datawith their own environmental measurements and become part of acitizen-science network. The selected project partners have contributed and exchanged particularknow-how and expertise in the fields of education, research, trainingand curriculum development. A broad range of Open EducationalResources have been elaborated (Intellectual Outputs IO1 – IO5).
