Inversion of GPS meteorology data
The GPS meteorology (GPS/MET) experiment, led by the Universities Corporation for Atmospheric Research (UCAR), consists of a GPS receiver aboard a low earth orbit (LEO) satellite which was launched on 3 April 1995. During a radio occultation the LEO satellite rises or sets relative to one of the 24 GPS satellites at the Earth's horizon. Thereby the atmospheric layers are successively sounded by...
متن کاملAtmospheric delay analysis from GPS meteorology and InSAR APS
Radar atmospheric decorrelation due to inhomogeneity of atmospheric refractivity is a critical limitation of satellite SAR interferometry (InSAR) in the high accuracy retrieving of geophysical parameters. With mm precision, a water vapor tracing technique based on GPS meteorology was widely employed to mitigate InSAR atmospheric errors. However, a reliable comparison of atmospheric delay betwee...
متن کاملRecent Ground Based GPS Meteorology Developments for SuomiNet
Over the past 10 years significant progress has been made in atmospheric sensing with GPS. Both spacebased atmospheric sounding and ground-based measurements of integrated delay due to the troposphere have shown promise for meteorological applications. Now the focus is shifting from developing and validating the sensing technology towards applying it to weather forecasting. This paper will focu...
متن کاملAccurate Rainfall Measurement: The Neglected Achilles Heel of Hydro-Meteorology
Rainfall measurement has an extensive historical precedent. Attempts have been made to standardise measurement procedures. This has never been successfully achieved. There are many sources of measurement error, some of which are compounded by poor rain gauge siting and a variation in gauge height. By far the worst cause of measurement inaccuracy is due to windinduced undercatching. Some solutio...
متن کاملGPS Meteorology' Remote Sensing of Atmospheric Water Vapor Using the Global Positioning System
We present a new approach to remote sensing of water vapor based on the global positioning system (GPS). Geodesists and geophysicists have devised methods for estimating the extent to which signals propagating from GPS satellites to ground-based GPS receivers are delayed by atmospheric water vapor. This delay is parameterized in terms of a time-varying zenith wet delay (ZWD) which is retrieved ...
