Dataset for: Statistical properties of meso-scale plasma flows in the nightside high-latitude ionosphere

This dataset is a compilation of statistical results from Gabrielse et al. [2018] (https://doi.org/10.1029/2018JA025440). If you would like to use the dataset, please contact Christine Gabrielse (cgabrielse@ucla.edu, cgabrielse@gmail.com). Depending on how the results are used, the main authors request co-authorship on publications. 

The following list describes the columns in each data file labeled, ***_FLOW-DATA-PCvsAO_YYYY.txt 
Files named  ***_FLOW-DATA-PCvsAO_YYYY_poleward.txt are for poleward-directed flows. 
Each text file is for a different year (YYYY). 
AO=auroral oval
PC=polar cap

The following list describes the columns in each data file labeled, ***_orientation_YYYY.txt 
Files named  ***_orientation_YYYY_poleward.txt are for poleward-directed flows. 
Each text file is for a different year (YYYY). 
The orientation was determined when enough bearings between RGs were available. See Gabrielse et al. [2018] for description.
