 Abstract: One-dimensional CSAMT and CSAMT-LOTEM joint inversion are implemented into an existing 1-0 joint inversion code. Instead of apparent resistivity and phase impedance, real and imaginary parts of the impedance are used as inverted data to avoid artificial data in near-field region and unsymmetrical scale between the two types of data. Since the values of the imaginary component can be negative, the inverse hyperbolises function is used to represent the logarithmic feature of the data. By testing to the synthetic data, the use of real and imaginary component of the impedance as inversion variables give relatively the same quality in estimating inverted model, but with less iteration number. The inversion routine is also successfully applied to the CSAMT and LOTEM data at Merapi both as singles and joint inversion.
