Lancet Planetary Health study says almost no one is safe from PM2.5

99% of the world's population is exposed PM 2.5 at unhealthy levels according to Lancet Planetary Health's recently released study. The Washington Post author Kasha Patel highlights:

In 2019, they found 0.001 percent of the global population is exposed to levels of PM 2.5 pollution that the World Health Organization deems safe. The agency has said annual concentrations higher than 5 micrograms per cubic meter are hazardous.

IMPROVE Data Publications

Job Opening: Postdoctoral Scholar Position

Postdoctoral scholar position: ASCENT - Atmospheric Science and mEasurement  NeTwork, FT-IR and ACSM Location: University of California, Davis

The Atmospheric Science and mEasurement NeTwork (ASCENT, link) is a new aerosol measurement network funded by the National Science Foundation Mid-Scale Research Infrastructure program.

Job Opening: Postdoctoral Researcher

Postdoctoral Researcher, New Instrument for Detecting Wine Grape Taint Location: University of California, Davis

Wildfires have devastated large swaths of the western states resulting in a range of catastrophic consequences. The wine grape growers and vintners in Washington, Oregon and California have lost hundreds of millions of dollars due to grapes that become unsuitable for wine due to damage from wildfire smoke.

Wildfire Resilient Structures Conference

Wildfire Resilient Structures (WiReS) Conference Date: Winter 2022/2023 Location: TBD Purpose

The Wildfire Resistant Structures (WiReS) conference addresses the WUI fire risk problems inherent to the built environment to support resilient and

19 From UC Davis in Global List of Most-Cited Researchers

Nineteen researchers from the University of California, Davis, have been named in the annual Highly Cited Researchers 2018 list released by Clarivate Analytics. The list identifies exceptional scientists and social scientists who have demonstrated significant influence by publishing multiple papers that rank in the top 1 percent by citations in a particular field and year, over a 10-year period. 

Multi-wavelength analysis of particle light absorption

This project is no longer running.

AQRC scientists have designed and built a new broad-band light source instrument to adapt the Hybrid Integrating Plate/Sphere Analysis (HIPS) light absorption measurement for a full spectrum of wavelengths throughout the visible and including the near IR and UV. Work is underway to develop approaches for calibration and for analysis of the data from this new spectrometer.

Evaluation of organic carbon measurements in the IMPROVE and CSN networks

The gain and loss of gaseous carbonaceous material from quartz filters can bias the measurement of organic particulate matter. The Air Quality Research Lab scientists have worked with others in the IMPROVE and Chemical Speciation Network (CSN) communities to investigate organic carbon measurement uncertainty related to determining a consistent method for estimating sampling artifacts and evaluating post-sampling losses during field latency and transport.

FT-IR Analysis of Teflon (PTFE) Filter Samples

FT-IR is a non-destructive which allows the filter samples to be analyzed by other non-destructive methods such as gravimetric for mass, XRF for elements, HIPS for light absorption, or destructive methods such as ion chromatography for ions or GC/MS for organic compounds after FT-IR analysis. FT-IR analysis and multivariate calibrations measure TOR-equivalent OC and EC, Functional groups such as aliphatic CH, carboxylic acids, carboxylates, non-acid carbonyl and alcohol OH (carbohydrates), Inorganic ions including sulfate, nitrate and ammonium, Soil elements and PM mass.
