大地电磁magnetotelluric数据NLCG反演预处理及后处理

详 情 说 明

In order to effectively interpret the Earth's subsurface, it is necessary to collect and analyze data using various methods. One such method is the use of magnetotelluric data, which can provide valuable information about the electrical conductivity of the Earth's crust and upper mantle. In particular, the use of large-scale controlled-source electromagnetics (CSEM) can greatly improve the resolution and accuracy of magnetotelluric data.

However, the processing and interpretation of magnetotelluric data can be complex and challenging. One approach that has been developed is the use of non-linear conjugate gradient (NLCG) inversion, which can help to improve the accuracy and reliability of the results. This involves pre-processing the data to remove noise and artifacts, and then using sophisticated algorithms to invert the data and produce a model of the subsurface.

To further enhance the reliability and accuracy of the results, it is also important to perform rigorous post-processing of the data. This can involve a variety of techniques, such as regularization, quality control, and uncertainty analysis. By carefully analyzing and interpreting the magnetotelluric data, it is possible to gain important insights into the structure and composition of the Earth's subsurface.
