GEMINI output used to develop volumetric reconstruction technique for EISCAT 3D

This dataset is used as a "ground truth" for investigating the performance of a volumetric reconstruction technique of electric current densities, intended to be applied to the EISCAT 3D radar system. The technique is outlined in a mnuscript in preparation, to be referred to here once submitted. The volumetric reconstruction code can be found here: https://github.com/jpreistad/e3dsecs

This dataset contain four files:

1) Dataset file 'gemini_dataset.nc'. This is a dump from the end of a GEMINI model run driven with a pair of up/down FAC above the region around the EISCAT 3D facility. Detailes of the GEMINI model can be found here: https://doi.org/10.5281/zenodo.3528915 . This is a NETCDF file, intended to be opened with xarray in python: 

import xaray

dataset = xarray.open_dataset('gemini_dataset.nc')

2) Grid file 'gemini_grid.h5'. This file is needed to get information about the grid that the values from GEMINI are represented in. The E3DSECS library (https://github.com/jpreistad/e3dsecs) has the necessary code to open this file and put it into the dictionary structure used in that package. 

3) The GEMINI simulation config file 'config.nml' used to produce the simulation.

4) The GEMINI boundary file 'fac_said.py' used to produce the boundary conditions for the simulation

Together files 3 and 4 could be used to reproduce the full simulation of the GEMINI model, which is freely available at https://github.com/gemini3d

The configuration files for this particular run are also available at this location:
