Conferencia impartida por la Dra. Gloria Titos.

Resumen: Atmospheric aerosols are able to scatter and absorb solar radiation. The magnitude of the radiative impact of aerosol particles depends on their concentration, their size and composition as well as on relative humidity (RH) due to water uptake. Knowledge of the scattering enhancement factor, f(RH), is important for an accurate description of direct aerosol radiative forcing. This factor is defined as the ratio between the scattering coefficient at enhanced RH to a reference (dry) scattering coefficient.
In this work we present a global picture of f(RH) measurements. The work is based on a recently re-analysed and harmonized dataset of humidified nephelometer measurements which is openly available. The measurements were performed at 26 sites which were mainly part of the ACTRIS and NOAA network.
