air quality from the smoke seems to post the most potential to impact outdoor sporting events.
from The Athletic:
According to air quality index (AQI) data from Plume Labs in El Segundo, Calif. — where the Chargers' practice facility is located — the area had an AQI value of 153 on Wednesday, which is considered unhealthy to breathe.
The Rams, who do not have an indoor facility, practice in Woodland Hills, where the AQI is 131, which can cause health effects for members of sensitive groups. The AQI value at SoFi Stadium — which is an open-sided stadium — was at 184 on Wednesday.
As of Wednesday afternoon, the Rams are still scheduled to practice Thursday in Woodland Hills, but are monitoring the air quality in the area.
According to AirNOW, a program from the U.S. Environmental Protection Agency (EPA) that provides air quality data, outdoor activities should be shorter and less intense once the AQI level tops 100. Above 150, people should avoid long or intense outdoor activities. And above 200, all people should avoid all physical activity outdoors.
“The NFL continues to closely monitor developments in the area and will remain in contact with both clubs and the NFLPA," a league spokesperson told The Athletic on Wednesday.
