Rainfall forecast based on GPS PWV together with meteorological parameters using neural network models

, 2021
In recent years, it has been found that the Precipitable Water Vapor (PWV) time series derived from ground-based GPS measurements can be used in to forecast precipitation in different regions.

Evaluating the Accuracy of Jason-3 Water Vapor Product Using PWV Data From Global Radiosonde and GNSS Stations

IEEE Transactions on Geoscience and Remote Sensing, 2020
Jason-3 is equipped with the Advanced Microwave Radiometer-2 (AMR-2) to account for the zenith wet delay (ZWD) caused by the troposphere in the altimeter signal, from which the precipitable water vapor (PWV) can be deduced.

Mean weighted temperature for PWV estimation

2015 IEEE 4th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2015
In this paper, the effects of mean weighted temperature (Tm) for the calculation of perceptible water vapor (PWV) from GPS data is analyzed. Tm for Singapore is estimated using surface temperature information (Ts). To analyze the effect of Tm for calculating PWV, PWV for four consecutive months are calculated using the estimated equation and compared ...

POOR AGREEMENT BETWEEN CAROTID-FEMORAL PULSE WAVE VELOCITY (C-F PWV) AND 24 HOUR PWV DETERMINED WITH TWO DIFFERENT METHODS

Journal of Hypertension, 2023
Objective: The gold standard of arterial stiffness determination is measurement of the carotide-femoral pulse wave velocity (cf-PWV). It was suggested that 24 hour measurement might give addition or more insights in the estimation of the global cardiovascular (CV) risk Our aim was to analyze association/concordance ...

Evaluation of GPS PWV anomaly during ENSO

Proceeding of the 2011 IEEE International Conference on Space Science and Communication (IconSpace), 2011
Water vapor variability during the El Nino-Southern Oscillation (ENSO) events from 2003 to 2007 were analyzed using an anomaly and a percentage method. ENSO indices and sea surface temperature anomalies (SST a ) were employed to detect the ENSO events.

GPS derived PWV for monitoring cloud evolution

2017 Progress in Electromagnetics Research Symposium - Fall (PIERS - FALL), 2017
Global Positioning System (GPS) Precipitable Water Vapor (PWV) values are widely used in monitoring climatic conditions. Mostly GPS PWV values are studied for rain forecasting. In this paper, we present results which support that the GPS PWV values can also be used to study the cloud evolution properties.

Wearable PWV technologies to measure Blood Pressure: eliminating brachial cuffs

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
The clinical demand for technologies to monitor Blood Pressure (BP) in ambulatory scenarios with minimal use of inflation cuffs is strong: new generation of BP monitors are expected to be not only accurate, but also non-occlusive. In this paper we review recent advances on the use of the so-called Pulse Wave Velocity (PWV) technologies to estimate BP ...

Multi- decadal variations and periodicities of the precipitable water vapour (PWV) and their possible association with solar activity: Arabian Peninsula

Journal of Atmospheric and Solar-Terrestrial Physics, 2019
In this study, radiosonde observations from seven sites in Saudi Arabia for the period 1985 to 2016 were utilized to investigate the interannual, monthly, and seasonal variations and trends of precipitable water vapour (PWV).

Cuffless blood pressure monitoring using PTT and PWV methods

2017 International Conference on Recent Innovations in Signal processing and Embedded Systems (RISE), 2017
Cuff based methods for measuring Blood Pressure (BP) are obtrusive and uncomfortable and demands continuous, non-invasive measurement methods. The aim of this work is to develop a platform that measures BP using indirect techniques such as Pulse Transit Time (PTT) and Pulse Wave Velocity (PWV) methods.
