GPS Tomography and Remote Sensing Techniques for Water Vapor Determination in the ESCOMPTE Campaign
نویسندگان
چکیده
The comparison of the integrated precipitable water vapor (IPWV) retrieved by GPS, microwave radiometer, solar spectrometer and radiosondes, operated within the French field campaign ESCOMPTE, shows an overall good agreement. The time dependent relative fluctuation as well as the absolute amount of water vapor match with high accuracy. The software package AWATOS (Atmospheric WAter vapor TOmography Software), developed at the Geodesy and Geodynamics Lab, ETH Zürich, is used to determine the spatial distribution and variation of water vapor in the troposphere by double differenced GPS measurements. The comparison with refractivity profiles derived from radiosonde data shows the success of this method.

3-D Water Vapor Tomography in Wuhan from GPS, BDS and GLONASS Observations
Three-dimensional water vapor can be reconstructed from Global Navigation Satellite System (GNSS) observations, which can study 3-D profile variations of atmospheric water vapor and climate. However, there is a large uncertainty of water vapor tomography from single GPS system observations due to limited satellites. The rapid development of multi-GNSS, including China’s Beidou Navigation Satell...
متن کاملSensing atmospheric structure: Tropospheric tomographic results of the small-scale GPS campaign at the Onsala Space Observatory
Tropospheric tomography using data from local networks of Global Positioning System (GPS) receivers is producing encouraging spatio-temporal representations of the wet refractivity field. In this work we present the results from a small-scale geodetic experiment that we carried out at the Onsala Space Observatory. Seven GPS receivers distributed within a radius of 3 km from the center, were dep...

Bamdzh wetland of Khuzestan Province is at downstream of Shavvr River. Its area is approximately 4 hectares. Due to the loss of wetland area, especially in recent decades, this study investigated the effects of a five-year drought (2007-2012) in the Shavvr region and the pond ultimately. Also the comparison between the satellite images and remote sensing technique has been used and was estimat...
متن کاملEstimation 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 کاملDetermination of Vertical Refractivity Structure from Ground-based GPS Observations
The primary scientific objective of this research is to develop GPS sounding techniques for ground based atmospheric refractivity sensing. Atmospheric profiling with GPS from space has been demonstrated (e.g. Rocken et al., 1997). Ground based receivers have been used to determine integrated atmospheric water vapor above a site, but profiling techniques with ground-based GPS observations are st...
