COMPUTER SOLUTION OF TRANSIENT AND QUASIEQUILIBRIUM ATMOSPHERIC DEIONIZATION EQUATIONS,

Two computer programs are described for use on the IBM-7047090 electronic data processing machines or any large computer accepting FORTRAN. The necessary modifications for use on these two computers are simple and self-evident. One of these programs deals with the numerical solution of the three equation, transient deionization phenomena. The second program deals with the solution of the deionization phenomena under quasiequilibrium conditions that are derivable from the three equation transient solution. The second quasi-equilibrium computer program also calculates 1 the modified collision frequency as effected by temperature and the presence of partial ionization, 2 the differential and integrated absorption of electromagnetic waves through the assumed ionosphere. Included also in these programs are other features described in this report that in their present form do not yield very useful information. Author
