Surface elevation changes of glaciers in the Cordillera Real and Tres Cruces, Bolivia, between 2000 and 2016 ...
During the last decades, climate change has led to a significant shrinkage of glaciers in the Tropical Andes. However, there is a lack of recent multi-temporal quantifications of ice mass loss at mountain range to regional scales. We measure temporally consistent glacier area changes and geodetic ma...

During the last decades, climate change has led to a significant shrinkage of glaciers in the Tropical Andes. However, there is a lack of recent multi-temporal quantifications of ice mass loss at mountain range to regional scales. We measure temporally consistent glacier area changes and geodetic mass balances throughout the Bolivian Cordillera Real and Tres Cruces based on multi-sensor remote sensing data in the period 2000-2016. By analyzing interferometric SAR data a geodetic mass balance of -399±98 kg m-2 a-1 and a total ice mass loss of 1.84±0.46 Gt is derived for 2000-2016. In more recent years, ice loss was above the average rate. A mass budget of -467±358 kg m-2 a-1 is found after 2013. These higher change rates can be attributed to the strong El Niño event in 2015/16.The data set consists of elevation change maps for each subregion (R1, R2, R3; see associated article) for the periods 2000-2013, 2000-2016 and 2013-2016.
