Abstract: The evaporation rates of small (radius 3?9 ?), freely failing water droplets were determined. The droplets, produced in a diffusion cloud chamber, were allowed to fall through air of known relative humidity (95?99%) and ...

Abstract: Experimental evidence for enhanced evaporation of small (3?9 ? radius) water droplets is presented. Both ?pure? droplets and droplets contaminated with surface active materials that were dropped into air of known relative ...

Abstract: The records from pollutant sensors abroad two aircraft are compared. The aircraft flew along arcs of either 80 or 120 km radius from the Gateway Arch in St. Louis. One aircraft contained a light-scattering instrument which ...
