Overview
This data set identifies the extent of supraglacial lakes (SGLs) from 1988 to 2023 on 769 of the largest debris-covered glaciers in the High Mountain Asia region. SGLs were generated via automated processing of 30 m Landsat imagery and are provided at 1-year intervals from 2004-2023, at 2-year intervals from 1992-2003, and as a single 4-year interval from 1988-1991.
