Individual replicate fits for aerosols. Columns show replicates, rows show virus (HCoV-19 112 above, SARS-CoV-1 below). Lines are 50 random draws per panel from the posterior distribution of fitted 113 lines, to show level of uncertainty.

SARS-CoV-2 was viable in aerosols throughout the 3-hour study (titer went from $10^{3.5}$ to $10^{2.7}$ $TCID_{50}$ per liter of air), as was SARS-CoV-1 (titer went from $10^{4.3}$ to $10^{3.5}$ $TCID_{50}$ per milliliter). The half-life of SARS-CoV-2 was 1.1-1.2 hours (95% credible intervals 0.64, 2.64).
