10 KC/S ATMOSPHERIC NOISE PREDICTIONS,

Abstract

This report contains a full set of atmospheric noise prediction maps for 10 kc/s. The procedure involved in transferring the 1 megacycle maps given for local time and seasonal periods in CCIR Report 322 to 10 kc/s maps given in Universal Time for three month periods is described in this report. A new approach to the prediction of VLF atmospheric noise was begun under this program and preliminary results are presented herein. The presentation of the CCIR data on a universal worldwide scale for a particular three month period revealed serious shortcomings and obvious disagreements with noise source and VLF propagation characteristics. The new technique begun makes direct use of noise source and propagation information. The preliminary results indicate that this technique may offer considerable advantages in the VLF range.
