uv run python scripts/loftgaedi.py — downloads bulk CSVs + API for recent data, outputs data/processed/reykjavik_pm10_daily.csv with PM10 + wind + weather joined.

Use Open-Meteo for historical daily wind speed in Reykjavik:

Low wind + dry = high PM10 (dust not dispersed). High wind can also resuspend settled dust.
