Fig. 1From: Spatial and temporal characteristics of optimum process noise values of tropospheric parameters for kinematic analysis of Global Navigation Satellite System (GNSS) sites in JapanMap of GNSS stations. Circles denote the GEONET stations used in this study. Solid green circles indicate the specific station locations used in “Results” and “Discussion” sections. Dashed red lines denote the sub-divided regions A–G used to assess the regional dependencies of tropospheric parametersBack to article page
