In the narrative of the “Tragedy of the Commons”,(1,2) a shared grazing area (aka common pool resource(3)) is trampled into overgrazed ruin by a pervasion of actors who exploit the resource more quickly than can be sustainably allotted. Regardless of whether there is consciousness of guilt, this is theft.
Air Quality Research Center ______, Sean Raffuse has been working on a team at NASA developing smoke and fire models. A recently published article quoted below shares his work over the past few years.
Ann M. Dillner, Associate Director of Analytical Research, contributed to a recently published study on biomass burning particulate emissions.
Particulate matter (PM) affects visibility, climate, and public health. Organic matter (OM), a uniquely complex portion of PM, can make up more than half of total atmospheric fine PM mass.
Year after year California has seen some of the largest and most deadly wildfires, not only by acreage burned, but by also by hazardous air quality. The smoke has turned some cities in neighboring state’s air quality into the dirties in the world, including outside of the state.
New research from Xiaolu Zhang, Krystyna Trzepla, Warren White, Sean Raffuse, and Nicole Pauly Hyslop
Thermal–optical analysis (TOA) is a class of methods widely used for determining organic carbon (OC) and elemental carbon (EC) in atmospheric aerosols collected on filters. Results from TOA vary not only with differences in operating protocols for the analysis, but also with details of the instrumentation with which a given protocol is carried out.
Roy Harrison, a researcher and professor at the University of Birmingham, UK, recently conducted a study to review the reductions in PM 2.5 and NO2 levels that resulted from the COVID-19 pandemic lockdowns over 11 cities. Harrison applied machine learning techniques to remove the effects of weather on the gaseous concentrations to see how the air quality had truly changed due to the lockdowns.
It’s widely known through the Air Quality Research Center that outdoor air pollution leads to untimely deaths throughout the world, however, a recent publication by Dr. Erwan Monier, Associate Professor of Climate Change Impacts in the Department of Land, Air and Water Resources, and associates demonstrated that many of these deaths are a result of cross-state air pollution.
A recent collaborative study between Harvard and UC Davis produced data backing the notion that nanoparticles (NP) more frequently crossed the air-blood lung barrier to the rest of the body in infant rats than adults. Fascinatingly, this higher permeability demonstrates immature lungs do not follow the same directives as mature lungs.
