Kinematic PPP time series example for station 0098 on March 10, 2011, based on the various process noise parameter combinations between zenith wet tropospheric delay and the tropospheric gradient (a–f). Red, green, and blue lines denote the east–west, north–south, and up–down components, respectively. TROP and GRAD shown at the top of each figure represent the process noise value for the zenith wet tropospheric delay and the tropospheric gradient, respectively
