![]() Los impactos resultantes en el ozono y PM2.5 fueron usados para cuantificar los impactos en la salud causados por los incendios de vegetación, usando el Programa Beneficios del Mapa y Análisis - Edición de la Comunidad. Adicionalmente, el sensor de bajo costo para determinar el particulado fino (PM2.5), tomado de la red PurpleAir, fue usado para mejorar el modelado de concentraciones de PM2.5. Este estudio usó el Inventario de Incendios de la base de datos del Centro Nacional para Investigaciones de la Atmósfera y del modelo Comunitario Multiescalar sobre la Calidad del Aire, para estimar los efectos de las emisiones de incendios sobre la calidad del aire desde el 16 de agosto hasta el 28 de octubre de 2020. ![]() Ese año, múltiples grupos de incendios en el norte de California rodeaban el área de la Bahía (Bay Area), cubriendo los cielos de humo y elevando las concentraciones de contaminantes hasta niveles peligrosos. Los incendios de vegetación en 2020 devastaron California, fijando el récord anual de área quemada hasta el presente. The integration of low-cost sensor data proved invaluable in refining the estimates of health impacts from PM2.5 resulting from wildfires. ![]() ![]() This suggests that widespread wildfire emissions can negate years of efforts dedicated to controlling air pollution. The increased hospital admissions and premature mortality attributed to wildfires were found to be comparable to the health impacts avoided by strategies aimed at meeting ozone and PM2.5 air quality standards. The correction using PurpleAir data increased estimates of wildfire-induced mortality due to PM 2.5 exposure by up to 16%. While modeled PM 2.5 concentrations were lower than measurements, correcting these with PurpleAir data improved the accuracy. Modeling results indicated that wildfires alone led to a rise in ozone daily maximum 8-h average by up to 10 ppb and exceeded PM 2.5 air quality standards in numerous locations by up to 10 times. Direct PM 2.5 emissions surged up to 38 times compared to an average day. Wildfire activity significantly increased direct PM 2.5 emissions and emissions of PM 2.5 and ozone precursors. The resulting impacts on ozone and PM 2.5 are used to quantify the health impacts caused by wildfires using the Benefits Mapping and Analysis Program – Community Edition. In addition, low-cost sensor data for fine particulate matter (PM 2.5) from the PurpleAir network is used to enhance modeled PM 2.5 concentrations. This study uses the Fire Inventory from the National Center for Atmospheric Research database and the Community Multiscale Air Quality model to estimate the effects of wildfire emissions on air quality during the period from August 16 to October 28 of 2020. Clusters of wildfires in Northern California surrounded the Bay Area covering the skies with smoke and raising the air pollutant concentrations to hazardous levels. The human-caused fire is under investigation, according to the San Bernardino National Forest.ĬNN’s Justin Lear, Susannah Cullinane and Alta Spells contributed to this report.Wildfires in 2020 ravaged California to set the annual record of area burned to date. “Today is the peak day of heat over the Labor Day weekend.”Īn evacuation order has been issued for the Oak Glen, Mountain Home Village, Forest Falls and North Bench Yucaipa communities. “Due to very dry vegetation, very steep terrain and very hot weather, the fire has been extremely active,” San Bernardino National Forest said in a news release. Meanwhile, some San Bernardino communities are being told to evacuate because of the El Dorado Fire, which has burned through 3,010 acres since it began Saturday morning.

Sustained wind speeds are about 10 to 15 miles per hour.Ĭalifornia is grappling with a relentless series of wildfires this summer, including many sparked by lightning. On top of that, “this is in a river canyon, so in the afternoon you get up-canyon winds,” Tune said. ![]() The National Weather Service issued an excessive heat warning for the region, with high temperatures ranging from 107 to 112 degrees slated to last until Monday night.
