Short summary

We performed a field campaign to measure the ice thickness of the Grigoriev ice cap (Central Asia). We interpolated the ice thickness data to obtain an ice thickness distribution representing the state of the ice cap in 2021, with a total volume of ca. 0.4 km³. We then compared our results with global ice thickness datasets composed without our local measurements. The main takeaway is that these datasets do not perform well enough yet for ice caps such as the Grigoriev ice cap.
