Dataset: Statistical survey of fine-scale auroral structure at high latitude: Evidence consistent with acceleration by dissipative non-linear inertial Alfvén waves.

Data set used in the paper: Statistical survey of fine-scale auroral structure at high latitude: Evidence consistent with acceleration by dissipative non-linear inertial Alfvén waves (Brindley, N; Whiter, D; Gingell, I). DOI: 10.1029/2025JA033715 ASK1_ASK3.zip Contains the Auroral Structure and Kinetics instrument observations. All files are background subtracted and sigma clipped (to remove stars). North is in the direction of increasing row number. Directory structure: 1. Camera 2. Aurora classification Example filename: 20141122130036r3_F207bkg_adj_w4clipping.csv 20141122130036 indicates the start time (UT) of a 20-minute data block (YYYYMMDDhhmmss). r3 indicates camera 3. 207 is the frame number emission_altitudes.zip Contains the modelled emission altitudes (in km). File structure: col1,col2,col3 data block,frame,emission altitudes Data blocks and frames correspond to those in ASK1_ASK3/ASK1/ dict_params.zip Contains metadata for each data block File structure: col1,col2,col3,col4,col5 data block and camera, counts to Rayleighs conversion factor, degrees per pixel, magnetic zenith x coord, magnetic zenith y coord
