On October 09, 2026, an analysis was conducted to assess the potential impact of nearby fire activity on ozone levels at Clovis - N. Villa Ave. 4 wildfires were detected within 100 miles of the site from two days before the event to the event day. The proximity of these fires to the site suggests they may have contributed to elevated ozone levels on this date. The following wildfires were identified: Dome Fire, which burned 6815.00, started on September 15, 2026, and last updated on October 07, 2026. It was located 52.2 miles away. Blind Fire, which burned 43.00, started on September 26, 2026, and last updated on October 07, 2026. It was located 96.2 miles away.
