Project description:
The water vapour plays a crucial role in atmospheric processes that act over a wide range of temporal and spatial scales, from global to micrometeorology. Therefore, a good knowledge of water vapour distribution in space and time is a fundamental requirement for several atmospheric applications. Relatively cheap and easy information on water vapour distribution can be derived from GNSS (Global Navigation Satellite Systems). Usually, GNSS refer to series of available constellations of which GPS (Global Positioning System) is the most famous. GNSS data can be extremely useful for the purpose of a multi-instrumental investigation; indeed, it was used to calibrate and validate other instruments (Campanelli et al. 2018) or methodologies (Rohm et al. 2011). It is therefore very important, and it is the aim of this project, to equip the Svalbard measurement site with at least one GNSS receiver, even just one low-cost single frequency, to complement, for example, the observations available for the boundary layer phenomena characterization.rnrnCampanelli, M., A.
