The Air District is encouraging residents to prepare for potential smoke impacts this summer to protect their health in the event of widespread unhealthy air quality.
The Air District and Alameda County District Attorney Ursula Jones Dickson filed a joint civil lawsuit against Radius Recycling, formerly Schnitzer Steel Industries, for air quality violations related to the fire at the company’s facility in West Oakland on August 9-10, 2023. In addition, previous enforcement actions by the Air District and the district attorney required Radius Recycling to install new equipment that has eliminated hundreds of tons of air pollution and reduced cancer risk by 84 percent since 2022; today the Air District finalized the operating permit for this important equipment.
The Air District is lifting an air quality advisory for the Bay Area due to wildfire smoke that was originally scheduled to last through today, Monday, July 14. Over the weekend, smoke from the Butler and Green wildfires had been moving down the Sacramento Valley and impacting air quality in portions of the Bay Area. However, as of Monday morning, the Bay Area is experiencing strong onshore winds, and smoke has remained mostly outside of the region. Air quality has been in the Good Air Quality Index category. Moderate onshore winds are expected to continue into Tuesday, keeping the smoke outside of the Bay Area. As the week progresses, these onshore winds will turn southerly in northern California, and this also is expected to keep the smoke from moving towards our region.

馬林縣西部海岸和南部常有涼爽的海洋空氣和濃霧。因為靠近海洋,這些地區的氣溫全年穩定。因為遠離海洋,馬林縣東面較為溫暖,少霧。距海洋較遠,使得海洋空氣在到達東部馬林城市之前升溫。整個縣的盛行風一般是西北風,西部海岸風速最高。山裡的年降雨量通常比灣區的大部分地方要高,平均在 37 到 49 英寸之間。該縣的大部分降雨發生在十一月到三月。
馬林縣 (San Francisco County) 的氣候還受到區域性灣區氣候的影響。
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。
沿著馬林縣海岸和馬林縣南部,來自太平洋的潔淨空氣幫助把空氣污染降到最低。在馬林的其他地方,偶爾才會出現臭氧問題,但丘陵地形和冬季較冷的氣候把 PM2.5 鎖在地表附近,致使空氣品質超過健康標準。
馬林縣的愛惜空氣資源團隊在當地社區倡導降低空氣污染的方法。
