land-based SSIP dataset is high-frequency and noisy. Data misfit sensitivity analysis for various objective measures suggests convergence in local minima. Thus, we implement the optimal transport (Wp) metric, which is known to have better convexity and convergence properties. We specifically adopt the trace-by-trace approach using the linear integral wavefield method to satisfy the data nonnegativity condition while also benefiting from enhancements in convexity resulting from the low-frequency boost. We show compressional wave speed sensitivity kernels in Imperial Valley.
