Short summary

The viscosity of erythritol, a tetrol found in aerosol particles, is highly uncertain. To help resolve this uncertainty, we measured the viscosities of erythritol–water particles using rectangular-area fluorescence recovery after photobleaching and aerosol optical tweezers techniques. These results should help improve the understanding of the viscosity of secondary organic aerosol particles. In addition, we present an intercomparison of techniques for measuring the viscosity of particles.
