PREPARATION OF A WORLD WIDE VLF EFFECTIVE CONDUCTIVITY MAP.
A map showing effective electrical earth conductivity values for a propagating wave at VLF (10 kHz to 30 kHz) has been prepared for the major land areas of the world. Land area conductivity determinations were in most cases based upon known geological and climatological information. Actual conductiv...
