Fig. 8From: Spatial and temporal characteristics of optimum process noise values of tropospheric parameters for kinematic analysis of Global Navigation Satellite System (GNSS) sites in JapanSpatial distribution of improvements in coordinate time series for each coordinate component on March 10, 2011, based on the estimated “common” optimum process noise values. The color of each circle indicates the improvement rate at each station. Warm and cold colors denote positive and negative changes, respectively, at each station. Three outlier sites, which show very large SD, are indicated with open circles Back to article page
