Short summary

The response of aerosol particles to changes in relative humidity (RH) is dependent on the hygroscopicity of the constituent chemical components. We present accurate measurements of the hygroscopic response of aerosols over a wide range in RH, extending up to the saturation RH. The chemical compounds studied include dicarboxylic acids, amino acids, sugars and polyols. These data provide a comprehensive source of data to help improve functional group activity models of aerosol hygroscopicity.
