Atmospheric anomalies over Mt.Etna using GPS signal delays and tomography of radio wave velocities
GPS atmospheric anomalies tropospheric delays tomography of radio wave velocities
2015/9/2
Due to the prominent topography of Mt. Etna, the use of satellite geodetic techniques may significantly suffer from atmospheric heterogeneities. This problem mainly affects the DInSAR technique. To ov...
Determining precipitable water in the atmosphere of Iran based on GPS zenith tropospheric delays
Precipitable water Zenith wet delay Radiosonde profiles GPS Modeling
2015/8/18
Precipitable water (PW) is considered as one of the most important weather parameters in meteorology. Moreover, moisture affects the propagation of the Global Positioning System’s (GPS) signals. Using...
