Data and code supporting climate-driven restructuring of snow- and ice-fed runoff in the headwaters of the Keriya River

This dataset supports the study entitled “Climate-driven restructuring of snow- and ice-fed runoff and its implications for water security in an arid inland river basin.” It contains the SPHY model configuration and calibrated parameters, documented processed-input information, historical and future runoff-component outputs, elevation-dependent results, numerical source data for Figures 1–12 and Tables 1–2, and preprocessing, statistical-analysis, and plotting scripts for the headwaters of the Keriya River. The historical study period is 1970–2019, and future projections extend to 2100 under the SSP2-4.5 and SSP5-8.5 scenarios. The complete daily 500 m meteorological forcing map stacks are not included because of their large data volume; information on the original data sources, processing procedures, representative summaries, and the preprocessing script is provided. Observed runoff data from Langan Hydrological Station are subject to data-use restrictions and are not publicly redistributed.
