An Improved Method for Rainfall Forecast Based on GNSS-PWV
Remote Sensing, 2022 Global navigation satellite systems (GNSS) has been applied to the sounding of precipitable water vapor (PWV) due to its high accuracy and high spatiotemporal resolutions. PWV obtained from GNSS (GNSS-PWV) can be used to investigate extreme weather phenomena, such as the formation mechanism and prediction of rainfalls.

Comprehensive Validation and Calibration of MODIS PWV over Mainland China
Atmosphere, 2022 Although ground-based precipitable water vapor (PWV) can be obtained with a high temporal resolution and spatial resolution of tens of kilometers in an urban area using Global Navigation Satellite System (GNSS) observation, it remains fairly sparse in ...

GPS derived PWV for rainfall monitoring
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Precipitable Water Vapor (PWV) is a good source to monitor precipitation. It is defined by the amount of water vapor present in atmosphere. Traditionally, radiosondes and microwave radiometers were used to derive PWV. However, these devices have poor temporal resolutions and high operational costs.

Research on methods of ABI and PWV measurement
2010 3rd International Congress on Image and Signal Processing, 2010ABI (ankle-brachial blood pressure index) and PWV (pulse wave velocity) are two major evaluating factors in vascular function test. Methods of blood pressure measurement both in time and frequency domain are introduced and compared for calculating ABI value.

Mean weighted temperature for PWV estimation
2015 IEEE 4th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2015In 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 ...

Evaluation of GPS PWV anomaly during ENSO
Proceeding of the 2011 IEEE International Conference on Space Science and Communication (IconSpace), 2011Water 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), 2017Global 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.
