A 1964 digital data base for ionospheric modeling. Part B: Incoherent scatter radar results

The Millstone Hill (Massachusetts) Thomson scatter results for March, April, June, September, and December of 1964 are assembled in digital form. These digital results are archived on magnetic tape. The density and temperature profiles extend from 90 to 1000 km. The profile results are digitized as observed over the height range from 200 km to 700 km. Monthly mean values are introduced, along with a model for the underlying ionization, to extend the lower portion of the density profiles. An exponential extrapolation extends the density profiles at the higher heights. The electron and ion temperature profiles are extended to lower and higher heights, to be consistent with the neutral atmosphere as given by the model of Jacchia.
