Mesoscale GPS Zenith Delay assimilation during a Mediterranean heavy precipitation event [PDF]

Advances in Geosciences, 2008
The impact of assimilating Zenith Total delay (ZTD) observations from a mesoscale ground-based GPS network over Western Europe is evaluated for the heavy precipitation event of 5–9 September 2005 over Southern France.

A Novel Enhancement of the MIMIC Remote Sensing Water Vapor Product and Its Application in GNSS Positioning

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Tropospheric delay plays a crucial role in global navigation satellite systems (GNSS) positioning, climate monitoring, and weather forecasting. In particular, in high-precision GNSS applications such as precise point positioning (PPP), prior tropospheric
