Importance of Tropospheric Correction to C-band InSAR Measurements: Application in the 2018 Palu Earthquake

Indonesian Journal of Geography, 2022
Long-term InSAR-based observations are prone to atmospheric delay interference. The active-phase signals emitted and recorded back by sensors during imaging are easily disturbed by the electron content in the ionospheric layer and the water vapor content

Estimating Zenith Tropospheric Delay Based on GPT2w Model [PDF]

IEEE Access, 2019
To precisely and conveniently estimate zenith tropospheric delay (ZTD), troposphere refractivity is deduced through global pressure and temperature 2w (GPT2w) model and surface meteorology devices, ZTD is estimated based on integration of refractivity in the zenith direction. When surface meteorological measurements are absent, all parameters including
