Web9 feb. 2024 · Abstract. The hygroscopic growth of atmospheric aerosols plays an important role in regional radiation, cloud formation, and hence climate. Aerosol hygroscopic growth is often characterized by hygroscopic tandem differential mobility analyzers (HTDMAs), and Xie et al. (2024) recently demonstrated that hygroscopic growth measurements of … Normally the heat transfer between airstreams provided by the device is termed as "sensible", which is the exchange of energy, or enthalpy, resulting in a change in temperature of the medium (air in this case), but with no change in moisture content. However, if moisture or relative humidity levels in the return air stream are high enough to allow condensation to take place in the device, then this will cause "latent" heat to be released, and the heat transfer material will be covered w…
