Understanding aerosols for pollution, climate change, and disease transmission
Jose-Luis Jimenez,
CU ANYL Faculty (1/2 seminar)
"Our group’s research focuses on understanding the sources, properties, transformations, and sinks of aerosols (and of the gases that interact with them), which have major effects on human health and climate. In this talk I will briefly present results from different projects over the last year, as well as some future directions for our group. I will introduce our aircraft research program, including results from the recent NASA/NOAA FIREX-AQ wildfire smoke study, where we obtained near-molecular level aerosol speciation data at 1 second time resolution. We are investigating both the inorganic and organic composition of the smoke, including important properties such as pH and volatility. I will summarize modeling work with GECKO-A exploring the evolution of OH reactivity with OH exposure for different hydrocarbons. I will discuss our indoor air research, including the apportionment of gases in the CU Art Museum combining 3 different CIMS instruments. I will also briefly describe recent developments on the importance of aerosols for disease transmission, not just for COVID-19 but for all (or most) respiratory diseases.
For those interested in COVID-19 aerosol transmission, you can find a summary of the evidence supporting airborne transmission of COVID-19 at https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)0086…, a review for airborne transmission of all respiratory diseases at https://doi.org/10.1126/science.abd9149 (starting Thu 26-Aug), and an overview of the historical reasons for the confusion on this topic at
