You can click on the counties of the Emergency Dept. Visits layer to show the expected number of
emergency department visits due to wildfire smoke exposure.
The Smoke Forecaster uses a health impact function to generate an estimate of how many
additional people might visit the emergency department for any respiratory health condition or for asthma
in particular.
This estimate is based on the concentration of wildfire smoke in the air, the typical
number of emergency department visits per day for county, the number of people
who live in the county, and the relationship between wildfire smoke and emergency department visits.
