High Temporal Resolution Refractivity Retrieval from Radar Phase Measurements [PDF]
Remote Sensing, 2018 Knowledge of the spatial and temporal variability of near-surface water vapor is of great importance to successfully model reliable radio communications systems and forecast atmospheric phenomena such as convective initiation and boundary layer processes.

Refractivity Observations from Radar Phase Measurements: The 22 May 2002 Dryline Case during IHOP Project [PDF]
Atmosphere, 2023 The dryline, often associated with the development of severe storms in the Southern Great Plains of the United States of America, is a boundary layer phenomenon that occurs when a warm and moist air mass from the Gulf of Mexico meets a hot and dry air ...

Statistics of Radio Refractivity Derived from Prague Radiosounding Data
Radioengineering, 2003 Vertical gradient of radio refractivity in the lowest 100 m isderived from the meteorological radio-sounding data of the Prague-Libusstation. The data cover the measurements at the terms 00, 06, 12, and18UTC, and the extent of data is 20 years.

A Multiscale Parametrization for Refractivity Estimation in the Troposphere [PDF]
, 2021 This paper presents the idea of multiscale parametrization for tropospheric refractivity inversion using gradient-based optimization method. Our motivation is to improve the accuracy of inversion without the use of apriori information.
