...some are bounced back to the starting point where the elapsed time is recorded while others escape into space. From this data the heights and densities of the layers can be calculated. Of the three major layers, said Dr. Berkner, the lowest (E) averages 65 miles high, the next (F1) 130 miles, the uppermost (F2) 190 miles. In summer the densities of these three, from top to bottom, are 16,000,000 ions, 5,300,000 ions and 2,800,000 ions per cubic inch. During the present sunspot cycle ionization has increased about 50% in the E and F1...
