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 ([e-mail], [e-mail]). 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 time [YYYYMMDDhhmmss] flagAO [-1=flow could not be observed. 0=flow could be observed, but was not. 1=flow was observed] flagPC [-1=flow could not be observed. 0=flow could be observed, but was not. 1=flow was observed] FWHMavg_AO [degrees] FWHMkmavg_AO=[km] longtestranges=[ignore] Velmaxavg_AO=[m/s, actual average of max V in each range gate used] VelmaxFITavg_AO=[m/s, determined from the Gaussian fits] FWHMavg_PC=[degrees] FWHMkmavg_PC=[km] Velmaxavg_PC=[m/s, actual average of max V in each range gate used] VelmaxFITavg_PC=[m/s, determined from the Gaussian fits] ;;For the bearings/orientation, see the orientation text files. The following four variables were calculated in a first step but are not ;;those used in the paper. They were not found with the strict selection criteria. Please do not use. mbearingAO=[degrees in magnetic coordinates, a negative value is South of East (clockwise from East), a positive value is North of East (CC)] mbearingPC=[degrees in magnetic coordinates, a negative value is South of East (clockwise from East), a positive value is North of East (CC)] gbearingAO=[degrees in geographic coordinates, a negative value is South of East (clockwise from East), a positive value is North of East (CC)] gbearingPC=[degrees in geographic coordinates, a negative value is South of East (clockwise from East), a positive value is North of East (CC)] ;;;;;;;;;;;;;;; minlatAO=[degrees, min geographic latitude of the flow] maxlatAO=[degrees, max geographic latitude of the flow] minlatPC=[degrees, min geographic latitude of the flow] maxlatPC=[degrees, max geographic latitude of the flow] mltAO=[degrees (MLT)] mltPC=[degrees (MLT)] AE=[nT] AL=[nT] SYMH=[nT] IMFBz=[nT] IMFBy=[nT] F107=[sfu] 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.
