Short summary

Fluorescent biological aerosol particles were measured in autumn over the continental United States at a variety of altitudes and temperatures, spanning the atmospheric boundary layer to the upper troposphere. Number concentrations of these particles generally decreased with height but were most variable at middle altitudes, above the boundary layer. This corresponds to the temperature range where biological particles may be more important than mineral dust at nucleating ice in clouds.
