Short summary
The response of airborne particles to relative humidity (RH) in the atmosphere, referred to as their hygroscopicity, is a key property that determines their water content. The hygroscopicity depends on the chemical species that make up the particle. Here, we investigate the growth in particle size and composition that occurs with increasing RH for particles containing a series of amine compounds and sulfuric acid, typical atmospheric components, providing a comprehensive and accurate data set.
