英文摘要	Based on the recently released National Glacier Inventory (NGI), we analyzed the characteristics and the mass balance rates of ice masses in the Argentinean Central Andes (ca. 30 degrees-37 degrees S). The NGI provides unprecedented information on area, number and distribution of different ice masses, including debris-covered glaciers and rock glaciers. In the Central Andes, a number of 8,076 ice masses were identified covering a total area of 1767 km(2). For the period 2000-2018, a general lowering of the ice surface was observed with a region-wide mass balance rate of -0.18 +/- 0.19 m w.e. yr(-1). Clear differences depending on the debris coverage of the different ice masses were identified, with mass balance rates ranging from -0.36 +/- 0.19 m w.e. yr(-1) for partly debris-covered glaciers to -0.02 +/- 0.19 m w.e. yr(-1) for rock glaciers. Considering different sub-periods, the region-wide mass balance rate was slightly positive (+0.12 +/- 0.23 m w. e. yr(-1)) from 2000 to 2009 and negative (-0.21 +/- 0.30 m w.e. yr(-1)) from 2009 to 2018. A comparison with the Randolph Glacier Inventory (RGI version 6.0) indicates that the NGI provides more detailed information regarding different type of ice masses whereas region-wide mass balance rates show limited sensitivity to the choice of the inventory. The inclusion of rock glaciers and debris-covered ice with rock glacier in the NGI causes mass balance rates to be slightly less negative than when using the RGI. Since the Central Andes are experiencing an unprecedented decade-long drought, our study provides crucial information to estimate current and future hydrological contribution of the different type of ice masses to river discharge in the arid subtropical Andes.
