Time series of atmospheric water vapour and troposphere zenith total delay, over Central and South America, from a homogeneous GNSS reprocessing (MAGGIA ZTD & IWV Solution 1)

open access: yes, 2016
Atmospheric water vapour has been acknowledged as an essential climate variable. Weather prediction and hazard assessment systems benefit from real-time observations, whereas long-term records contribute to climate studies.

Establishment of a new global model for zenith tropospheric delay based on functional expression for its vertical profile

open access: yes, 2014
The tropospheric delay is one of the most significant error sources for radio navigation and space geodetic techniques. Its value is seriously affected by the height of the observing object.
