Abstract

Geophysical measurements of electrical conductivity, magnetic fields, and gamma radiation at the Oak Ridge Reservation exhibited multifractality (fractal and multiscaling), to varying degrees, in both the north-south and east-west directions. The multiscaling was anisotropic, and the underlying statistics of the fields were in general non- Gaussian. We fitted the multifractal model of Schertzer and Lovejoy to the data. The model appears to be able to simulate a wide range of fields and to reproduce the negative skewness of the data histograms. For brevity, only our analysis of the magnetic data is reported here.
