AB: GPS observation in Wuhan IGS station has been carried since 1998. The linear trend of non-atmospheric vertical crustal displacement there is determined as -6.43+/-0.20 mm/year. During the same period, gravity observation using a superconduting gravimeter has been operated in Wuhan Jioufeng station, 15 km far away from the IGS GPS station.The non-atmospheric trend predicted from the SG observation is -5.94+/-0.11 mm/year, which is almost the same as that determined by GPS.
