Remote sensing-derived time series of transient snowline altitudes for High Mountain Asia, 1986–2021

Abstract

This study presents a new dataset of remote sensing-derived Transient Snowline Altitude (TSLA) measurements for glaciers in High Mountain Asia. We use the Google Earth Engine to obtain TSLA data for approx. 28 · 104 glaciers larger than 0.5 km². After filtering and postprocessing, the dataset comprises ca. 9.66 million TSLA measurements with an average of 341 ± 160 measurements per glacier, covering the time span 1986 to 2021.
