Fig. 8From: Data assimilation experiment of precipitable water vapor observed by a hyper-dense GNSS receiver network using a nested NHM-LETKF systemFlowchart illustrating how the localization radii in the SLOC experiment were determined. R m and R o indicate precipitation intensity observed by weather radar at the analysis grid point, and the GNSS station, respectively. The character “r” indicates the localization radius needed to assimilate RHmod data converted from the GNSS-derived PWVBack to article page
