In this study, the Zenith Tropospheric Delay ( ZTD) for ERA-Interim was assessed by ZTD from sev-en IGS sites over mainland China in 2011 .The results show that the mean yearly BIAS and RMS for the ERA-Interim ZTD are better than 1 cm and 2 cm respectively.Besides, there are no obvious seasonal characters.
