This dataset relates to quality control during the accuracy validation study of 3D electromagnetic forward modeling.
The research team used the 3D electromagnetic forward modeling program developed by the project to calculate the electromagnetic response of a homogeneous half-space model. Experts evaluated the accuracy indicators by comparing the differences between 3D numerical simulation results and 1D numerical simulation results. The homogeneous half-space model was spatially discretized using COMSOL software; input information such as transmitter length, transmitting current intensity, and receiver position were designed to form the 3D electromagnetic forward modeling input files. The 3D numerical simulation program developed by the project was run to calculate and obtain the electromagnetic response of the homogeneous half-space geoelectric model. The error of the 3D electromagnetic forward modeling was calculated; the response curve characteristics of the 1D and 3D numerical simulation results were compared to analyze the reliability of the 3D numerical simulation results.

The dataset was generated via experimental tests by the third-party institution Jilin Provincial Institute of Electronic Information Product Inspection, which possesses professional qualifications including CNAS. The institution conducted inspection and testing strictly in accordance with the expert-validated test outline, referencing the implementation standards GB/T 25000.51-2016 and GB/T 25000.23-2019. The test results were reviewed and finally confirmed by a panel of experts.
