RISDeveloping an Operational, Surface-Based, GPS, Water Vapor Observing System for NOAA: Network Design and Results
Publisher: American Meteorological Society
Abstract: The need for a reliable, low-cost observing system to measure water vapor in the atmosphere is incontrovertible. Experiments have shown the potential for using Global Positioning System (GPS) receivers to measure total ...
A Lightning Prediction Index that Utilizes GPS Integrated Precipitable Water Vapor
Publisher: American Meteorological Society
Abstract: The primary weather forecast challenge at the Cape Canaveral Air Station and Kennedy Space Center is lightning. This paper describes a statistical approach that combines integrated precipitable water vapor (IPWV) data from ...
Short-Range Forecast Impact from Assimilation of GPS-IPW Observations into the Rapid Update Cycle
Publisher: American Meteorological Society
Abstract: Integrated precipitable water (IPW) estimates derived from time delays in the arrival of global positioning system (GPS) satellite signals are a relatively recent, high-frequency source of atmospheric moisture information ...
The Validation of AIRS Retrievals of Integrated Precipitable Water Vapor Using Measurements from a Network of Ground-Based GPS Receivers over the Contiguous United States
Publisher: American Meteorological Society
Abstract: A robust and easily implemented verification procedure based on the column-integrated precipitable water (IPW) vapor estimates derived from a network of ground-based global positioning system (GPS) receivers has been used ...
Developing a Performance Measure for Snow-Level Forecasts
Publisher: American Meteorological Society
Abstract: The snow level, or altitude in the atmosphere where snow melts to rain, is an important variable for hydrometeorological prediction in mountainous watersheds; yet, there is no operational performance measure associated ...
National Weather Service Forecasters Use GPS Precipitable Water Vapor for Enhanced Situational Awareness during the Southern California Summer Monsoon
Publisher: American Meteorological Society
Abstract: uring the North American Monsoon, low-to-midlevel moisture is transported in surges from the Gulf of California and Eastern Pacific Ocean into Mexico and the American Southwest. As rising levels of precipitable water ...
The Amazon Dense GNSS Meteorological Network: A New Approach for Examining Water Vapor and Deep Convection Interactions in the Tropics
Publisher: American Meteorological Society
Abstract: he complex interactions between water vapor fields and deep atmospheric convection remain one of the outstanding problems in tropical meteorology. The lack of high spatial?temporal resolution, all-weather observations in ...
