Is it possible to forward model and invert VLF in-phase and quadrature data using simpeg?
examples of instruments that collect VLF data are the Geonics EM-16 Geonics Limited - VLF Receivers, and the GEM GSM 19 VLF https://www.gemsys.ca/quotations/request-a-quote-for-vlf-em-3-frequency-system-or-vlf-em-2d-resistivity-software/ .
I have both synthetic data and measured data that I could share if there is interest.
