Supporting data and code for observation-constrained blowing-snow reconstruction across the Central Asian Water Tower

This dataset contains supporting data and code for the evaluation of blowing-snow mass flux and visibility predictions at monitoring sites. The deposited materials include model validation results at hourly and daily temporal scales, summary performance metrics, variable definitions, and documentation of the processing workflow. The analysis compares process-based mass-flux estimates with machine-learning-corrected predictions and evaluates visibility estimates against available observations. The dataset supports the station-based model evaluation described in the associated research. It does not, by itself, constitute the complete gridded dataset for the 1991–2025 regional reconstruction. Please consult the README and variable dictionary for file descriptions, units, temporal coverage, and usage instructions.
