Short summary
Using the arithmetic averages of precipitation isotope values, Wu et al. (2017) concluded that the Badain Jaran Desert (BJD) groundwater is recharged by modern local meteoric water. However, based on weighted mean precipitation isotope values, our further analysis shows that modern precipitation on the Qilian Mountains is more likely to be the main source of the groundwater and lake water in the BJD, as found. We believe this comment provides an important improvement for their study.
