Comparison of Tropospheric Signal Delay Models for GNSS Error Simulation [PDF]
Journal of Astronomy and Space Sciences, 2009 As one of the GNSS error simulation case studies, we computed tropospheric signal delays based on three well-known models (Hopfield, Modified Hopfield and Saastamoinen) and a simple model. In the computation, default meteorological values were used.

Method for improving the accuracy of calculating the tropospheric delay in satellite radio navigation using Kalman filtering [PDF]
E3S Web of Conferences, 2023 A method is proposed for improving the accuracy of calculating the tropospheric delay in satellite radio navigation using Kalman filtering with a combination of calculation using one of the standard troposphere models.

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

Simultaneous Retrieval of PWV and VTEC by Low‐Cost Multi‐GNSS Single‐Frequency Receivers
Earth and Space Science, 2019 Precipitable water vapor (PWV) and ionospheric vertical total electron content (VTEC) are two essential components of space‐atmosphere parameters. The zenith troposphere delay can be converted into PWV, which plays a crucial role in meteorological ...

Tropospheric wet path-delay measurements [PDF]
IEEE Transactions on Antennas and Propagation, 1982 A dual-channel microwave radiometer measuring the sky brightness temperature at the frequencies 21.0 and 31.4 GHz, an infrared spectral hygrometer (IRSH) measuring the ratio of the radiation from the sun at the wavelengths 931 and 880 nm, and radiosondes have been used simultaneously to determine the excess path length due to water vapor (wet path ...

Asymmetry in the effect of North Atlantic sea surface temperature on the eddy‐driven jet
Quarterly Journal of the Royal Meteorological Society, EarlyView.Projections of climate over Europe and the Atlantic are uncertain due to the uncertainty surrounding future changes in North Atlantic sea surface temperatures (SSTs). Here, we demonstrate that warming in the North Atlantic Ocean is linked to a transition to a negative phase of the North Atlantic Oscillation, as well as to an equatorward displacement of
