Enhanced zenith wet delay modelling for geodetic applications

Popis výsledku v původním jazyce

Invited presentation at the EUREF 2014 Symposium. Abstract: The troposphere modelling is a limiting factor in GNSS positioning. The main difficulty resists in the modelling of 10 % of the total path delay, so called wet path delay, due to temporally andspatially variable moisture in the atmosphere. It can not be precisely modelled from in situ observations and additional information about the vertical profile is important, at least. Until recently, external meteorological data were not considered as helpful for the wet delay modelling in positioning. With recent improvements in quality and temporal and spatial resolution of numerical weather models, these might be suitable for a future support of kinematic GNSS positioning including airborne applications. In past decades, various models for zenith wet delay (ZWD) were derived, but the most commonly used one was developed 25 years ago by Askne and Nordius (1987). Their analytical formula is highly suitable for designing a tropospheric
