Evaluation of ocean tide loading effects on GPS-estimated precipitable water vapour in Turkey

open access: yesGeodesy and Geodynamics, 2016
Global Positioning System (GPS) has been widely used to estimate the total zenith tropospheric delay (ZTD) and precipitable water vapour (PWV) for weather prediction and atmospheric research as a continuous and all-weather technique. However, estimations

Comparison of Tropospheric Horizontal Gradients Modeling Methods in LEO Constellation Augmented GNSS Precise Point Positioning

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
With the improvement in GNSS data processing accuracies, the selection of optimal asymmetric troposphere delay modeling method becomes essential, especially during the period of severe weather events and with the development of low Earth orbit (LEO ...

Variability of GPS-derived zenith tropospheric delay and some result of its assimilation into numeric atmosphere model [PDF]

open access: yes, 2012
The total zenith tropospheric delay (ZTD) is an important parameter of the atmo- sphere and directly or indirectly reflects the weather processes and variations.
