Dataset for journal paper "Fine-scale electric fields and Joule heating from observations of the Aurora"

Abstract

To be published in the Journal of Geophysical Research: Space Physics In article "Fine-scale electric fields and Joule heating from observations of the Aurora" we have combined Southampton led Auroral Structure and Kinetics (ASK) instrument with careful modeling to obtain high resolution electric fields associated with small-scale auroral features. We have combined our measurements with Scanning Doppler Imager (SCANDI) to obtain Joule heating estimates and compare them with more commonly used averaged SuperDARN measurements. Our results show that observation of small-scale Joule heating gives much higher values than the one obtained from averaged radar data. Dataset used in the article is available at: https://doi.org/10.5258/SOTON/D2501. Dataset consist of 3 files: ASK.zip, SuperDARN.zip, SCANDI.zip. ASK.zip has 3 folders: ASK1, ASK2 and ASK3. Each folder contains the files from separate ASK camera as explained in the paper. Data are stored in .txt files each labeled with the timestep. Each .txt file contains 256x256 matrix with pixel values obtained during given timestep. SCANDI.zip contains a .xlsx file with all the measurements from a single measurement sweep needed to obtain neutral wind velocity data presented in the paper. SuperDARN.zip contains the typical SuperDARN toolkit .grdmap and .map data types.
