Short summary

Marine aerosols play a critical role in weather and climate, and their real part of the refractive index (RRI) is a key factor in their radiative effects. We present a study of RRI measurements using optical tweezer technology and find that the calculated results of RRI using the traditional method disagree with the measurements. A parameterization of the RRI and relative humidity relationship is proposed, and it will improve the radiation calculation in numerical models.
