Zenith total delay interpolation to support GNSS monitoring of potential precipitations
, 2017 A useful contribution to atmosphere monitoring may be provided by the analysis of GNSS (Global Navigation Satellite System) signals. The authors have identified a procedure to monitor in space and time the Precipitable Water Vapor (PWV) content on regionally extended and orographically complex area.

The Oncologist, EarlyView., 2021 Abstract Background Medullary thyroid cancer (MTC) standard of care includes multikinase inhibitors (MKIs), which can exacerbate disease‐related diarrhea, primarily because of non‐RET kinase inhibition. We report diarrhea and other patient‐reported outcomes (PROs) with selpercatinib, a highly selective RET inhibitor, among patients with RET‐mutant MTC ...

Data assimilation of GNSS zenith total delays from a Nordic processing centre [PDF]
Atmospheric Chemistry and Physics, 2017 Abstract. Atmospheric moisture-related information estimated from Global Navigation Satellite System (GNSS) ground-based receiver stations by the Nordic GNSS Analysis Centre (NGAA) have been used within a state-of-the-art kilometre-scale numerical weather prediction system.

Retrieval of a High-Precision Drought Monitoring Index by Using GNSS-Derived ZTD and Temperature
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Potential evapotranspiration (PET) is a key parameter for calculating drought monitoring index that is generally difficult to obtain. In addition, PET has low spatial resolution and can only be obtained at a site-based point.

General Survey of Large-scale Land Subsidence by GACOS-Corrected InSAR Stacking: Case Study in North China Plain [PDF]
Proceedings of the International Association of Hydrological Sciences, 2020 Satellite-based InSAR (Interferometric Synthetic Aperture Radar) provides an effective way to measure large-scale land surface motions. Currently, the atmospheric phase delay is one of the most critical issues in InSAR deformation monitoring.
