Video sequences of microdroplets impacting on four surfaces of different wettability: - near-superhydrophilic surface (Video 1-A), sticking droplet - hydrophilic surface (Video 1-B), sticking droplet - hydrophobic surface (Video 1-C), bouncing droplet - superhydrophobic surface (Video 1-D), bouncing droplet. Impact sequences were analyzed using ImageJ-Trackmate plugin: - Example of impact on the superhydrophobic surface with single-particle tracking (Video 2) Experimental conditions: Wind speed: 10 m/s Operating temperature: 20 deg Celcius Captured on a Photron SA1.1 at 54000 fps. Video processing: background substraction. Video frame rate: 1 fps Scalebar: 100 micrometers Videos can be viewed online on youtube via the following link: https://www.youtube.com/playlist?list=PLmcZ2GRv9_bhySseXNuwONZLrvkuJ3aEg
