Session 3.3 GNGTS 2024 confictng borehole informaton. A similar approach is implemented in EEMverter also for automatc processing of AEM data (2021). Examples of joint inversion of AEM, ground EM and galvanic IP data through EEMverter is presented in Daut et al. (2024) in applicatons related to mineral exploraton and in Signora et al. (2024) for the characterizaton of the HydroGeosITe, the Italian reference and calibraton site for hydrogeophysical methods under development in Brescia, Italy. Figure 3.

Conclusions We presented EEMverter, a novel inversion sofware for electric and electromagnetc data with focus on induced polarizaton. Three distnctve features have been implemented in EEMverter: i) 1D, 2D and 3D forward modelling can be mixed sequentally or simultaneously in the iteratve process within multple inversion cycles, for diminishing the computatonal burden; ii) the joint inversion of AIP, ground EM-IP and ground galvanic IP data is fully supported with a common IP parameterizaton; iii) tme-lapse inversions of AIP, EM and galvanic IP data is possible with both sequental and simultaneous approaches. We believe that EEMverter, with its common inversion environment for the IP inversion of inductve and galvanic data will help in closing the gap between electric and electromagnetc data in AEM applicatons.
