Hi Dave,

I know that Rich Corsi at PSU (https://twitter.com/CorsIAQ) is working on this very topic, and should have something soon that will be extremely useful as it relates to higher ed campus operation and management of SARS-COV-2 transmission. It looks like Imke provided some great references, two others you might take a look at are:

Reducing transmission of SARS-CoV-2 (https://science.sciencemag.org/content/early/2020/06/08/science.abc6197)
The coronavirus pandemic and aerosols: Does COVID-19 transmit via expiratory particles? (https://www.tandfonline.com/doi/full/10.1080/02786826.2020.1749229)

From a data perspective on airborne transmission, I would try to find materials/analysis where they are taking a closer look at the outbreak in the call center in South Korea. Also, the choir outbreak in Washington state is another one. I personally don't believe these two events can be solely explained by droplet transmission.

Hope this helps,
Chris
