The Chicago Council on Science and Technology is hosting a virtual event for the public on air quality, with HAQAST student Aryiana Moore! Join online August 28th, 7:00 pm CT to learn more about work being done to understand and improve air quality! c2st.org/event/every-br…

Interested in how geostationary satellites are improving public health? Read how applying satellite data could potentially avert 1,200 PM2.5 -attributable premature deaths per year from severe air pollution events. buff.ly/3YHOuhA

New paper! Interested in the effect of Alaskan wildfires on air pollution? Read how HAQAST researchers provide a method to estimate surface PM2.5 from satellite aerosol optical depth (AOD). buff.ly/3MnsRMw Jingqiu Mao Pawan Gupta

Interested in the progression of urbanization under a changing climate? Read how Christopher Uejio and Leiqiu Hu propose the "ground urban heat island", an effective satellite-based measure to improve the representation of human-relevant heat exposure. buff.ly/3yM92eA

Learn how HAQAST PI Randall Martin and other researchers investigate the sensitivities to model resolution of geophysical satellite-derived PM2.5 inferred from satellite AOD retrievals and the simulated PM2.5 to aerosol optical depth (AOD) relationship. buff.ly/4fNqRKP

Check out this publication by HAQAST PI Bryan Duncan and other researchers which outlines the efforts underway to combine model forecasts, satellite retrievals and surface-based measurements to provide more accurate and accessible estimates of air quality. buff.ly/3yGWm8J

Looking to learn more about secondary inorganic aerosol formation and nitrogen deposition? Read how HAQAST-2 members Mark A. Zondlo and Da Pan found that rapid emissions reductions of SO2 and NOx shifted SIA formation and nitrogen deposition regimes. buff.ly/3WRxQuO

Satellite data can help fill the research gap on comparing injustices in NO₂ and PM2.5-attributable health burdens. Check out this article from HAQAST researchers to learn more about NO₂-attributable health impacts across the entire U.S. buff.ly/3A8AbbJ

Check out this publication featuring HAQAST PI Randall Martin which improves on estimations of global concentrations of PM2.5 from 1998-2019. buff.ly/46KqGvF

Learn how HAQAST researchers compared regression methods to estimate surface nitrogen dioxide concentrations at 0.01° resolution using satellite and land use data. buff.ly/4e00KPa

Mentor applications are now open for our Summer 2025 Fellowship Program, designed to encourage & support undergraduate students from backgrounds underrepresented in the environmental health sciences! Deadline for applications is Oct 25. Learn more: tinyurl.com/mryrj592
