How to estimate air
quality based on visibility for areas without an air quality monitor or airport
visibility estimate:
- Face away from the sun.
- Determine the limit of your visible range by looking for targets at known distances (miles).
- Visible range is that point at which even high contrast objects totally disappear.
- Use the values above to determine the local forest fire smoke category.
