This package contains a climatological model of the Equatorial
Electrojet. It is a model of four parameters: longitude, local time,
season, and F10.7. Included in the package are the coefficents
for the mean model and standard deviation model, along with
source code required to plot one dimensional slices of the model
for any desired parameter.

WINDOWS Users
=============

A windows executable "eej_plot.exe" is included. The windows
executable is a DOS program, so it needs to be executed in a DOS
window.

To compile source code under Unix:
==================================

The GNU Scientific Library (v1.9) is required for compiling this source
code. See http://www.gnu.org/software/gsl/

Once GSL is installed, simply typing 'make' will compile
all files and create the executable "eej_plot". This program
can be used to generate 1D plots of the EEJ model for any
choice of parameters with any of the four parameters as the plotting
variable.

Execute eej_plot -h to find out all the command line options for
how to specify parameter values.

Notes regarding using the source routines in your own work
==========================================================

The important source code files you'd need to include in your
own work are:

eej_calc.c   - contains routines for computing the EEJ mean and
               standard deviation

eej_basis.c  - contains the basis functions for each parameter
               in the model

eej_plot.c   - this is an independent driver program which will
               demonstrate how to call the routines in eej_calc.c

other        - the other source files contain various computational
               routines needed by the model
