title: Flow Channels Detected in SuperDARN Longyearbyen data 2016-2018

description: The algorithm for detecting ionospheric flow channels (FCs) described in Herlingshaw et al., 2019 (https://doi.org/10.1029/2019JA026916) was applied to 2 years of SuperDARN Longyearbyen data (2016-2018).<br>This pandas data frame provides information about the detected flow channels. The description of the variables inside are as follows:sd: start time and dateed: end time and datedur: duration [mins]rad: the radar code ('lyr' for all in this dataset)<br>by: a 15 minute average of the interplanetary magnetic field By component before the start time of the FC [nT]bz: a 15 minute average of the interplanetary magnetic field By component before the start time of the FC [nT]clockAngle: the interplanetary magnetic field clock angle calculated using by and bz [degrees]alpha: angle used to easily plot the clock angle onto a polar grid [degrees]<br>colat: the average magnetic colatitude of the center of the FC over the event [degrees]colatMax: the maximum magnetic colatitude of the center of the FC over the event [degrees]colatMed: the median magnetic colatitude of the center of the FC over the event [degrees]colatMin: the minimum magnetic colatitude of the center of the FC over the event [degrees]colatStd: the standard deviation of the magnetic colatitude of the center of the FC over the event [degrees]<br>mlat: the average magnetic latitude of the center of the FC over the event [degrees]mlatMax: the maximum magnetic latitude of the center of the FC over the event [degrees]mlatMed: the median magnetic latitude of the center of the FC over the event [degrees]mlatMin: the minimum magnetic latitude of the center of the FC over the event [degrees]mlatStd: the standard deviation of the magnetic latitude of the center of the FC over the event [degrees]<br>mlt: the average magnetic local time of the center of the FC over the eventmltMax: the maximum magnetic local time of the center of the FC over the eventmltMed: the median magnetic local time of the center of the FC over the eventmltMin: the minimum magnetic local time of the center of the FC over the eventmltStd: the standard deviation of the magnetic local time of the center of the FC over the event<br>mltPlt: the angle used to easily plot the average magnetic local time of the center of the FC over the event on a polar gridmltMaxPlt: the angle used to easily plot the maximum magnetic local time of the center of the FC over the event on a polar gridmltMedPlt: the angle used to easily plot the median magnetic local time of the center of the FC over the event on a polar gridmltMinPlt: the angle used to easily plot the minimum magnetic local time of the center of the FC over the event on a polar gridmltStdPlt: the angle used to easily plot the standard deviation of the magnetic local time of the center of the FC over the event on a polar grid<br>v: the average velocity of the FC over the event [m/s]vMed: the median velocity the FC over the event [m/s]vPeak: the maximum velocity of the FC over the event [m/s]vTrough: the minimum velocity of the FC over the event [m/s]vStd: the standard deviation of the velocity of the FC over the event [m/s]<br>width: the average width of the FC over the event [km]widthMax: the maximum width of the FC over the event [km]widthMed: the median width of the FC over the event [km]widthMin: the minimum width of the FC over the event [km]widthStd: the standard deviation of the width of the FC over the event [km]
