Glacier inventory is the basic data for hydrological, water resources and climate change research. Glacier inventories have been created for the Third Pole Region (TPR) or high Asia, yet they are different in coverage area and vary largely in quality. It is thus necessary to assess their quality in order to provide information for potential users to choose the right glacier inventories. Using the analytic hierarchy process, this study selects eight assessment factors and assesses the comprehensive quality of eight glacier inventories of the TPR by grading. The assessment results indicate that the comprehensive quality of the small-scale glacier inventories of WHGI, KPGI, PGI-2 and SETPGI is generally higher than that of the large-scale ones of RGI, GGI18, CGI-2 and HKHGI. Of the latter, the quality-ranking order from high to low is CGI-2, GGI18, RGI and HKHGI. However, the comprehensive quality of CGI-2 and GGI18 is comparable over the CGI-2 area. The comprehensive quality of CGI-2, GG
