WebEM techniques use a grounded electric dipole as a source that is energized with an alternating current at a given frequency to produce time-varying electric and magnetic fields that can be measured on the earth’s surface. The primary field spreads out in space and can penetrate the ground. WebThe Ultraviolet Index (UVI) is a rating scale, with numbers from 1 to 11, which indicate the amount of skin-damaging UV rays reaching the Earth’s surface during the day. The daily UVI forecasts ...
