DHS Brings Web App to Coronavirus Fight

The Department of Homeland Security, through its Science & Technology Directorate, has released a web app to help predict the decay rate of coronavirus in the air. The tool, entitled "Estimated Airborne Decay of SARS-CoV-2," accounts for the ambient temperature, relative humidity, and UV index in an outdoor environment to determine how much exposure time is required to "inactivate" certain proportions of aerosolized coronavirus.
