Grid for Auroral models
Discretizations of space (grids) and time conversions useful for aeronomy and auroral modeling.
Install
python m pip install e .
Note: you will need a Fortran compiler on your system for f2py
modules.
It works on Linux, Mac, Windows, etc.
Eigenprofiles
Currently GLOW and ReesSergienkoIvanov are available (Transcar in future). You can install these models with
pip install e .[models]
Once installed, select model by:

M rees
ReesSergienkoIvanov 
M glow
Stan Solomon's GLOW model
Command Line Options
t time, format yyyymmddTHH:MM:SSZ where Z sets UTC time zone c lat, lon WGS84 geodetic degrees o output, hDF5 ends in .h5 M model select (see table above) z min,max altitude to plot [km]
Example Command
python MakeIonoEigenprofile.py t 20130131T09:00:00Z c 65 148 o out.h5 M rees
Auroral Data Files
The functions in gridaurora/calcemissions.py
, based on work by
Zettergren, computes perwavelength volume emission rate along a flux
tube as a function of altitude along the tube. Starting with quantities
such as neutral densities computed by MSIS, differential number flux as
a function of energy and altitude along the tube (this is what TRANSCAR
computes), excitation cross sections as a function of energy,
FranckCondon factors and Einstein coefficients, the prompt volume
emission rate may be computed.

Einstein coefficient matrix A
arranged A(𝜈',𝜈'') where:
 𝜈' upper state vibrational levels, excited from ground state 𝜈''' by particle impact
 𝜈'' lower state vibrational levels, decayed into from the upper state
as discussed in Appendix C of Zettergren PhD thesis, Eqn. (C.2), photon
volume emission rate follows the relation P𝜈',𝜈'' = A(𝜈',𝜈'')
n𝜈'
lamdba
wavelength in nanometers corresponding to the Einstein coefficient
matrix A
except atomic
that uses the reaction rates directly.
FranckCondon factor fc
as described in Zettergren thesis Appendix C, specifically for Eqn (C.6C.8), the FranckCondon factors modify the total upper state excitation cross section multiplicitively.
