<Summary>The open source Video In Situ Snowfall Sensor (VISSS) is a novel instrument for the characterization of particle shape and size in snowfall. 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). ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.994111"!</Summary>
