Estimation and Analysis of Precipitable Water Vapor Using GPS Data and Satellite Altimeter
Determination of water vapor in the atmosphere plays an important role in forecasting weather conditions and precipitation studies. For this reason, it is very important to study the tropospheric delay, especially the wet component, which is due to the presence of water vapor in the atmosphere. In this paper, the amount of water vapor was estimated by altimeter satellite radiometer and GPS data...
متن کاملMeasurements 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...
متن کاملThe short-term temporal spectrum of precipitable water vapor.
Short-term power spectra of the fluctuations in the precipitable water vapor measured with a dual-channel microwave radiometer are presented. The spectra, taken over 34-hour sampling periods, encompass periodicities from I day to about 10 minutes. The fluctuation power is associated with the average precipitable water vapor for the sampling period. The background noise spectrum of the radiometr...
متن کاملThe 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...
متن کاملPrecipitable Water Vapor from Radar and 6.7 M Radiometer Comparison of Precipitable Water Vapor Observations by Spaceborne Radar Interferometry and Meteosat 6.7 M Radiometry
Satellite radar interferometry (InSAR) can be applied to study vertically integrated atmospheric refractivity variations with a spatial resolution of 20 m and an accuracy of 2 mm, irrespective of cloud cover or solar illumination. The data are derived from the diierence between the radar signal delay variations within the imaged area during two acquisitions with a temporal separation of one or ...
