Readme file describing the dataset used in paper “Fine-scale electric fields and Joule heating from observations of the Aurora”

Dataset used in the article is available at: https://doi.org/10.5258/SOTON/D2501

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 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. In each folder data is saved as a list of files named as askX_YYYY.txt, where X is replaced with the number of the camera, and YYYY is the number of timesteps after the start of the megablock. Megablock started on 2014.12.21 at 22:39:18 UT, and timestep is 0.05 seconds. Each .txt file contains 256x256 matrix with pixel values obtained during given timestep.

SuperDARN.zip contains 20141221.grdmap file with all the values and 20141221.fit08.map file which is used to plot the figure in the paper.

SCANDI.zip contains WNM14C21_windfit.xlsx file with all the measurements from a single measurement sweep needed to obtain neutral wind velocity data presented in the paper.
