Satellite data have long been recognized as valuable for air quality applications. These applications are in a stage of rapid growth: new geostationary satellites provide hourly or sub-hourly data; improvements algorithms convert measured wavelengths into retrievals atmospheric constituents; advances machine learning support improved estimates near-surface pollution; and growing interest among managers has led to range satellite Considering mainly activities the United States under Clean Air Act, we discuss proven relevant management, including: informing epidemiological studies health risk assessments setting regulatory standards; evaluating models; constraining emissions inventories; supporting Exceptional Event Demonstrations through tracking wildfire plumes other sources; characterizing emission patterns ozone-forming chemistry State Implementation Plans; improving forecasting; long-term trends evaluate impact. professionals increasingly using these related analyses, but barriers remain.

Beta attenuation monitors (BAMs) are widely used for the regulatory monitoring of fine particulate matter (PM2.5) and fence line industrial sites. The elemental analysis BAM filter tapes potentially could enable additional source PM2.5 attribution. However, chemical characterization glass fiber filters is hindered by high background metal values. A sample preparation method was developed using ultrasonic extraction from spots in nitric acid metals inductively coupled plasma–mass spectrometry (ICP-MS) scanning electron microscopy–energy-dispersive X-ray spectroscopy (SEM-EDS). To demonstrate utility this method, were analyzed wildfire smoke periods San Francisco Bay Area California Fall 2023 indicated elevated levels chromium compared to a non-wildfire period Spring 2023. SEM-EDS tape probe individual morphology, but it only detected Fe Ba at above blank media. be future events extend beta monitor monitoring.
