A New Method for Determining an Optimal Diurnal Threshold of GNSS Precipitable Water Vapor for Precipitation Forecasting [PDF]
Remote Sensing, 2021 Nowadays, precipitable water vapor (PWV) retrieved from ground-based Global Navigation Satellite Systems (GNSS) tracking stations has heralded a new era of GNSS meteorological applications, especially for severe weather prediction. Among the existing models that use PWV timeseries to predict heavy precipitation, the “threshold-based” models, which are ...

Diurnal cycle of precipitable water vapor over Spain [PDF]
Quarterly Journal of the Royal Meteorological Society, 2011 AbstractKnowledge of the diurnal cycle of precipitable water vapor (PWV) is very limited owing to the lack of data with sufficient temporal resolution. Currently, GPS receivers have proven to be a suitable technique to determine PWV diurnal variations. In this study, the annual and seasonal diurnal cycles of PWV have been obtained from GPS data for 10 ...

Atmospheric water vapor and precipitation coupling in Southwestern South America [PDF]
Geophysical Research LettersStudies linking atmospheric water vapor and precipitation have often focused on short records, tropical regions, and the Northern Hemisphere. Long-term variability of water vapor and its link to precipitation is less understood, especially in areas with strong latitudinal and climatic gradients. Here we analyze over 15 years of precipitable water vapor

Analysis of the distribution of precipitable water vapor in the Chajnantor area [PDF]
Radio Science, 2016 AbstractIn this work, we present results from a long‐term precipitable water vapor (PWV) study in the Chajnantor area, in northern Chile. Data from several instruments located at relevant sites for submillimeter and midinfrared astronomy were processed to obtain relations between the atmospheric conditions among the sites.

Statistical modelling of atmospheric mean temperature in sub-Sahel West Africa
Scientific African, 2020 Atmospheric mean temperature Tm, is a vital parameter in the evaluation of precipitable water vapor (PWV) through the analysis of GPS signal, it is therefore important to have a good way of evaluating Tm for the eventual accurate evaluation of PWV using ...
