Assessment of high-order ionopsheric effects on GPS-estimated precipitable water vapor

Abstract

The precipitable water vapor (PWV) can be estimated from dual-frequency GPS observations, which has been widely used for atmospheric study and weather forecasting. However, high-order ionospheric delays are normally ignored in GPS applications. In this paper, high-order ionospheric effects on GPS-estimated precipitable water vapor are investigated from 30… (More)
