| Popis: | During the International Geophysical Year, two series of balloon flights were made. One of these sampled the ionization due to cosmic rays over the range of geomagnetic latitudes from 38°N to 87°N. The other covered the range from 13°N to 79°S. In each case similar balloon flights from a base station were made to make possible an allowance for changes in the primary radiation. The second series of nights is used in this paper to determine the location of the knee of the latitude curve at atmospheric depths from 10 to 220 g cm−2. The results indicate that at this time of the solar cycle the knee moved toward the pole with decreasing amount of air overhead, reaching a geomagnetic latitude of 55° at 10 g cm−2. This movement of the knee becomes very slow at the lower pressures, however, suggesting that even at much lower pressures, the knee would not move appreciably farther toward the pole. |
