Print out files QUICKSTART, README and glow.txt Copy all the files to a directory Copy nrlmsise00.f and iri90.f to the directory or tell the compiler where they are Copy the IRI data files to another directory Rename the example program dayexample.driver to dayexample.f Edit the IRI call in dayexample.f to specify the IRI data file directory Compile and link *.f in Fortran 77 with -O3 optimization Run the executable (a.out) with input from dayexample.in, i.e.: a.out < dayexample.in > test1.out Compare the output you get to dayexample.out If it looks reasonable, try making some plots For auroral runs, change aurexample.driver to aurexample.f, compile, link, and: a.out < aurexample.in > test2.out Compare the output you get to aurexample.out Try some runs with your own input parameters Now try making some modifications to the example program to suit your purposes You can also run it all out of IDL using: spawn, './a.out < input.file > output.file' To perform high-energy aurora calculations: change the name of hexexample.driver to hexexample.f edit the glow.h file comment out the standard parameters comment in the high-energy parameters re-compile all subroutines, link, and: a.out < hexexample.in > test3.out compare to hexexample.out
