Code and data supporting "Atmospheric and terrestrial water interventions for dryland water security"

This repository contains the Python code, constructed inputs, and numerical outputs supporting Text S1 and Table 2 of the manuscript “Atmospheric and terrestrial water interventions for dryland water security”. The example links water-delivery accounting with a closed basin water balance. It compares a baseline with two intervention portfolios: an assigned cloud-related precipitation increment combined with runoff capture, and the same combination with atmospheric-water harvesting. Three constructed periods represent normal conditions, moderate dryness, and severe drought. The package includes the calculation script, an independent audit script, input and parameter tables, period-level results, scenario summaries, the numerical table corresponding to Table 2, a variable dictionary, and structured JSON results. All numerical inputs are hypothetical and expressed in arbitrary volume units. They are not observational or experimental data, forecasts, or estimates of actual intervention performance or drought risk. Requirements: Python 3.10 or later; no third-party packages are required. Run constructed_scenario.py to generate the outputs, then independent_audit.py to check the exported results.
