Suffering Air Quality Starts the Week for Yosemite After Wildfire

As wildfires continue to burn out in uncontrollable dry weather on Sunday, a thick layer of toxic air in California’s Yosemite National Park puts the air quality above 200 acres.

Yosemit visitors are advised to limit or stop outdoor activities at the National Park.

Air quality index 200 ፡ unhealthy

As wildfires spread through the Sierra Nevada Basin to the Tahoe Basin and its suburbs, air quality in and around the park became extremely unhealthy.

According to Robert Baruffaldi, a forecast for the Sacramento Office of the National Weather Service, the smoke will continue to blow northward.

Due to strong winds from the Pacific Ocean on Sunday, smoke was not expected to reach the San Francisco Bay Area. As the Monday winds unfold, Sote air can begin to flow into the Gulf area.

The Montreal Office said in a statement on Twitter that smoke was moving north but could reach the Gulf on Monday.

An air quality indicator of 0 to 500 is used to determine the amount of pollution in the air. Air pollution levels and health risks increase with EIA values.

The popular website PurpleAir has seen more than 200 and 150 AQI ratings in the vicinity of the park in 6 hours. API 150 is still described as “unhealthy” even though it is mostly for people with certain emotions. Bear Valley and Kirkwood had air quality readings between 100 and 110, while most areas near Lake Tahoe had readings between 50 and 75, with some places more than 100.

PurpleAir metrics are constantly updated and averaged over the last 10 minutes. AirNow statistics – PurpleAir statistics are calculated in real time and averaged over the last 10 minutes. Using advanced algorithms based on APA standards, it uses short averages during stable air quality and rapid change in air quality. Results are delayed compared to PurpleAir but updated hourly.

Purpler sells proprietary sensors to individuals to monitor pollution worldwide. According to SF Gate, people can place them indoors or outdoors as they choose.

The sensors use a laser particle meter to count the number of particles and then use a algorithm to determine mass concentration based on the count. They are different from air-sensing sensors that measure particles by passing air through a filter before measuring it.

At the southern end of the park, near Mariposa Grove, a 1,591-acre Washburn fire broke out Sunday afternoon, endangering 500 giant Sequoia trees.
