KnowAir Air Quality — Station-Based AQI Forecast

Query comprehensive air quality forecasts from monitoring stations with up to 15-day coverage using the Caiyun Weather API.

Prerequisites

1. A valid Caiyun Weather API token set as CAIYUN_TOKEN environment variable, or stored in ~/.config/knowair/token.
2. Coordinates (longitude, latitude) for the target location.

Quick Start

python3 scripts/query_air_quality.py --lng 116.3176 --lat 39.9760

Workflow

1. Resolve coordinates — convert city name to coordinates if needed.
2. Run the script:

   python3 scripts/query_air_quality.py --lng <LNG> --lat <LAT>
   

3. Present results — summarize current AQI level, pollutant trends, best/worst periods, and health advice.

Options
