Requires Python 3.10+ with numpy, pandas, scipy, and matplotlib.

Run python3 analysis.py from this directory.

The script reads raw/USW00094728.dly and regenerates annual_metrics.csv, quality_checks.csv, quality_checks.json, trend_results.csv, and trend_robustness.png.

SOURCE_DATES.txt records URLs, retrieval time, server metadata, and the raw-data version. REPORT.md contains the interpretation and limitations.
