Abstract : The VLF stmospheric noise prediction model described by Maxwell, et al was used to compute the expected direction of arrival of atmospheric noise energy. The energy arriving in each 10 degree azimuthal sector was determined and was related to effective field intensity in dB relative to one microvolt per meter in a one kilohertz bandwidth. In other words, if the receiving antenna has unity gain over a 10 degree sector and zero gain in all other directions, the field intensity indicated on these plots would be observed.
