Horizontal distance dependency of correlation coefficient of ZWD within the Uji network. The ZWD was converted from the SPD with the GNSS satellite at the highest elevation angle. Observational periods during 0000–0300 LT (green), 0300–0600 LT (red), and 0600–0900 LT (blue) on August 14, 2012, corresponded to weak rain, heavy rain, and no rain periods at RISH, respectively. Curves are fitted second-degree polynomials
