The Air District is lifting an air quality advisory for wildfire smoke that was originally scheduled to last through tomorrow, Wednesday, August 27.
The Air District has announced a $13.3 million grant to the San Mateo County Transit District toward the installation of new high-capacity electric bus charging infrastructure at its San Carlos facility. This SamTrans project will help accelerate the transition of the SamTrans bus fleet to zero-emission technology and improve air quality in communities most affected by air pollution.
The Air District is extending an air quality advisory due to wildfire smoke from the Pickett Fire through Wednesday, August 27. Smoke from the Pickett Fire in Napa County is expected to impact Napa, Solano and Sonoma counties through Wednesday. Conditions can change rapidly and the amount and location of smoke at ground level is hard to predict. The public can check for real-time smoke pollution levels in their local area with the U.S. EPA’s Fire and Smoke Map. Smoky, hazy skies may be visible, and the smell of smoke is possible.

索諾瑪縣 (Sonoma County) 的氣候很大程度上受到佩塔盧馬 (Petaluma)、科塔蒂 (Cotati) 和索諾瑪峽谷 (Sonoma valleys) 地形的影響。佩塔盧馬和科塔蒂峽谷裡的氣溫接近,而索諾瑪峽谷相對較為溫暖,與納帕谷接近。夏季,夜間溫度適中,白天炎熱;冬季,夜間涼爽,白天氣溫適中。佩塔盧馬和科塔蒂峽谷的風向規律受到佩塔盧馬峽口的強烈影響,聖羅莎和佩塔盧馬以無風到輕風為主。夏季傍晚時分,佩塔盧馬和科塔蒂峽谷常常起霧,並一直持續到次日午間之前。索諾瑪峡谷的陽光充沛。佩塔盧馬的年降水量為 24 英寸,索諾瑪 29 英寸,聖羅莎 30 英寸。

臭氧和細顆粒物污染(即 PM2.5)是影響舊金山灣區的主要區域性空氣污染物。臭氧問題主要發生在夏季,細顆粒物污染主要發生在冬季。
雖然索諾瑪縣內的大部分地方在夏季會變得十分炎熱,但空氣監測結果顯示,這一地區的臭氧水平在整個灣區是最低的。夏季除了最熱的幾天以外,新鮮的海風會從西面山脈之間的峽口吹向內陸。
節假期間,尤其是因為木材焚燒等,PM2.5 水平會上升,但空氣監測結果再次顯示,該地區的 PM2.5 水平在整個灣區最低。
