The NSF National Center for Atmospheric Research (NCAR) invites you to the Explorer Series lecture, “What clear skies can teach us: A history of urban air quality” on Wednesday, May 14 from 7:00-8:30 pm (MT). 

This event will be a live hybrid webcast with options to attend in person at the NSF NCAR Mesa Laboratory or virtually. Please register and tell us if you will be attending in person or online.

Event Summary

Spring 2020. Streets were clear due to the COVID-19 shelter-in-place orders. The skies were clear too…or were they?  This unprecedented shift in human activity gave scientists a chance to test hypotheses about air quality in urban settings and ask questions about the contribution of various sources to pollutants, such as ozone and particulate matter, in the past, present, and future.

In her Explorer Series lecture, Dr. Kelley Barsanti will discuss her work in the Los Angeles Basin during and after the COVID-19 pandemic, as well as decadal trends in urban air quality based on long-term and historic measurements.

Free public event recommended for ages 12+
