Data and Analysis Scripts for Multiscale Coupling of Boundary Layer Flow Turbulence and Sand Streamer Dynamics

This dataset provides synchronized high-speed video records of aeolian sand transport patterns (streamers) and high-frequency wind velocity data. The dataset includes raw experimental footage, 3D wind velocity components, and the core algorithm for streamer feature extraction. LongFootageFixedPlanGrayNearFrames11160Through12159.avi : Raw experimental video (grayscale). It represents a continuous observation segment (Frames 11160 to 12159) during the experiment. uvwWindSpeed_30Hz.mat : A MATLAB file containing three-dimensional wind velocity components. streamer.m : MATLAB processing script. This script is the core algorithm used to process the grayscale frames from the video file.
