The VISSS consists of two cameras with LED backlights and telecentric lenses that allow accurate sizing and combine a large observation volume with relatively high resolution and a design that limits wind disturbance. Here, movies and images of falling precipitation particles are provided for station Hyytiälä in November 2024 - December 2025. For further details on the VISSS instrument see Maahn et al. (2024).
