Synthetic Dataset 1D of Reflectivity Profiles with Corresponding Velocity and Density Models

This dataset contains a collection of synthetic reflectivity profiles and their corresponding subsurface velocity and density models. A total of 100,000 one-dimensional lithological models, each composed of 5 layers, were generated with variable layer thicknesses, random velocity gradients, and sharp contrasts to simulate realistic geological conditions. Each model was discretized into 50 uniform blocks of 100 m each, representing a total modeled depth of 5,000 m. For each block, both velocity and density values were assigned based on predefined ranges. The reflectivity profiles have a time sampling interval (Δt) of 0.002 s.
