| PM10 | Spring dust from studded tires. EU 24h limit: 50 µg/m³ |
| PM2.5 | Fine particles. EU annual limit: 25 µg/m³ |
| NO2 | Traffic. EU 1h limit: 200 µg/m³ |
| H2S | Geothermal (Hellisheiði). Nuisance smell at 5 µg/m³ |

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:
https://archive-api.open-meteo.com/v1/archive?latitude=64.13&longitude=-21.90&start_date=2024-01-01&end_date=2024-12-31&daily=wind_speed_10m_max,wind_speed_10m_mean,precipitation_sum&timezone=Atlantic/Reykjavik
Low wind + dry = high PM10 (dust not dispersed). High wind can also resuspend settled dust.
