Atmospheric Noise Levels at Radio Frequencies near Darwin, Australia

Abstract

Between August 25, 1944, and October 31, 1945, a practically continuous record of the average level of atmospheric radio noise at a frequency of 1.93 Mc/s. was obtained near Darwin, in north-western Australia. A few measurements were also made at a frequency of 5.9 Mc/s. The noise-measuring programme is described and the results obtained are presented graphically.
