Synergetic Use of GPS Water Vapor and Meteosat Images for Synoptic Weather Forecasting

The Westford Water Vapor Experiment: Use of GPS to Determine Total Precipitable Water Vapor

The Westford WAter Vapor Experiment (WWAVE) was designed to measure the temporal and spatial variability of the total precipitable water vapor over an area within a 25 km radius of the Haystack Observatory in Westford, MA. The main experiment was conducted from August 15 to August 30, 1995, and a variety of different techniques were used to measure the water vapor, including: radiosondes, launc...

A Comparison of Water Vapor Derived from GPS Occultations and Global Weather Analyses

Despite its fundamental importance in radiative transfer, atmospheric dynamics and the hydrological cycle, atmospheric water is inadequately characterized particularly at a global scale. Occultation measurements from the Global Positioning System (GPS) should imporve upon thids situation. Individual occultations yield profiles of specific humidity accurate to -0.2 gkg providing sensitive measur...

GPS Water Vapor Estimation Using Interpolated Surface Meteorological Data from Australian Automatic Weather Stations

The existing GPS tracking networks established primarily for surveying, geodesy and navigation purposes may also be used for meteorology studies. This research uses hourly surface temperature and pressure (T & P) observations from Australia for GPS Precipitable Water Vapor (PWV) estimation. The paper outlines the basic meteorological data requirements, and presents experimental results to show ...

Measurements of Precipitable Water Vapor by GPS, Radiosondes, and a Microwave Water Vapor Radiometer

Results from the Westford WAter Vapor Experiment (WWAVE) will be discussed. This experiment was designed to measure the temporal and spatial variability of the total precipitable water vapor (PWV) over an area of roughly 25 km radius around the Haystack Observatory in Westford, MA. The main experiment was conducted from August 15 to August 30, 1995, and a variety of techniques were used to meas...
