Sonoma Technology, Inc.

WOEIP and Sonoma Technology are working together to monitor air pollution in West Oakland. Sonoma Technology’s contribution includes (1) planning and implementing neighborhood air quality monitoring for criteria pollutants and toxic metals, (2) analyzing the benefits of street sweeping as an air pollution mitigation tool, and (3) educating students about air quality through our Kids Making Sense program. This project will lay the scientific foundation for community action in West Oakland to mitigate traffic-related pollution problems. Sonoma Technology can help you develop and implement a similar monitoring project for your community.

As Fourth of July celebrations approach, fireworks emissions continue to pose a challenge for air quality. Sonoma Technology meteorologist Jeff Beamish shared his insights with the San Francisco Chronicle 👉 https://lnkd.in/g67EJ7WM

Congratulations to Nathan Pavlovic and Fred Lurmann for their outstanding collaboration with scientists at the Keck School of Medicine of the University of Southern California! Their recent research demonstrates a direct connection between childhood air pollution exposure and adult bronchitis symptoms, highlighting the long-term impact of environmental factors on lung health.

One of the most dangerous consequences of climate change is the sudden presence of a #wildfire. In the University of California, Berkeley's Epidemiology and Computational Biology department, scientists are working hard to uncover how wildfire smoke affects the DNA of people living in the county of Alameda. 🔥🔬 The research team, including researchers from Sonoma Technology, Inc., the National Human Genome Research Institute (NHGRI), and Stanford University, will examine samples from 5,000 adults in the East Bay at two time points in 2020 and 2021–coinciding with the largest wildfire year in California history. Gather the details on the upcoming project by reading more.

Sonoma Technology is assisting CCEJN with modeling and analysis of warehouse and truck emissions in the South Central Fresno region. This study will investigate the impact of current and proposed warehouses on community exposure to air pollution. We will also analyze the benefits of various mitigation options, such as enhanced vehicle electrification and implementation of a warehouse indirect source rule (ISR) similar to an existing South Coast Air Quality Management District rule. This project is funded by the supplemental environmental funds program (SEP) through the California Air Resources Board.

Sonoma Technology developed a wildland fire data assimilation methodology incorporating multiple satellite sources (Terra MODIS, Aqua MODIS, SNPP VIIRS, NOAA-20 VIIRS) and agency records. Recent efforts further incorporated geostationary satellite data (GOES-E ABI, GOES-W ABI) to enhance spatial resolution, temporal resolution, and fire activity tracking completeness. This dataset includes growth areas, perimeters, and cross-referenced fire information from agency reports. The novel spatiotemporal resolution and methodological consistency of our dataset enables advances in historical fire-weather analysis, fire-weather modeling, characterizing wildfire growth potentials, historical/future smoke modeling, and near-real-time (NRT) fire monitoring.

Source apportionment is a powerful tool that can be used to analyze air, water, and soil quality data sets to determine pollutant sources. Sonoma Technology has worked with EPA's Office of Research and Development to develop EPA’s Positive Matrix Factorization (PMF) source apportionment model and associated guidance on its use. The last time the PM2.5 standard was changed, Sonoma Technology performed source apportionment of PM2.5 concentrations to identify sources of emissions and conducted supplemental analyses to support the development of State Implementation Plans (SIPs) using the EPA PMF model. Analyses included examining inter- and intra-urban trends of PM2.5 concentrations and its components, developing PM2.5 source profiles, and performing detailed analysis of the PMF results. https://lnkd.in/gYfTvtrX

Over the weekend, the #PointFire ignited in northern Sonoma County. Smoke from this fire will impact Napa and Sonoma Counties through tonight, with possible light smoke as far south as San Francisco and San Jose by sunrise Tuesday. By Tuesday afternoon, smoke will impact northern Sonoma and Napa Counties. Stay up-to-date on the latest Bay Area Air Quality Management District smoke forecast at https://lnkd.in/gmS6JZmv.
