Surface consistent amplitude corrections are commonly used to correct for the amplitude variations due to near-surface conditions in land processing. Usually, the corrections for PP and PS datasets are computed separately. There are, however, sound geophysical reasons why a subset of these scalars should be common or shared between PP and PS data. The simultaneous joint estimation of the source and receiver correction scalars for PP and PS datasets that we propose is a way to ensure the consistency of the surface-consistent corrections for both datasets. It also enables to compute a better estimation of the source term which must be identical for PP and PS traces originating from the same shot to be in accordance with the surface-consistent model.
