Air Days

These tile layers represent Air Days for orange and red days by a specific year.

Values represented in these tiles are based on the number of poor air quality days with the severity of orange or red in a year by severity. Each severity level includes days in that bracket and all days with worse air quality.

Example: days with orange severity include days with orange, red, purple, and maroon colors.
