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 Ny-Ålesund from January 2025 to December 2025. For further details on the VISSS Sensor see Maahn et al. (2024). The data from 2025-08-12 19:00 UTC to 2025-09-11 9:00 UTC is not usable due to processing issues.
