Methods and systems performing joint inversion determination of surface-consistent amplitude corrections are provided. A method includes receiving a seismic data set including P-P data and P-S data, and preparing the P-P data and the P-S data for a joined inversion to produce prepared P-P data and prepared P-S data. The method further includes performing a joined inversion on both the prepared P-P data and the prepared P-S data to calculate final surface consistent scalars. The method also includes outputting a corrected P-P trace determined from the P-P data and a P-P gain obtained from the final surface consistent scalars, and a corrected P-S trace determined from the P-S data and a P-S gain obtained from the final surface consistent scalars.
