title: Dataset For: Statistical Properties Of Meso-Scale Plasma Flows In The Nightside High-Latitude Ionosphere

description: 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 <br>
Files named  ***_FLOW-DATA-PCvsAO_YYYY_poleward.txt are for poleward-directed flows. <br>
Each text file is for a different year (YYYY). <br>

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