Data-based modeling of the magnetosheath magnetic field

The zip-archive 2023JA031665.zip contains two data files used in the generation and validation of the magnetosheath magnetic field model, a corresponding format description file, and a file with a fortran subroutine that can be used to reconstruct the magnetosheath magnetic field, as presented in the JGRA article 2023JA031665 by N. A. Tsyganenko, V. S. Semenov, and N. V. Erkaev "<strong><em>Data-based modeling of the magnetosheath magnetic field </em></strong>". Below is a list of files with a brief explanation of their content and purpose. 1. The ascii files <strong>Grand_training_set.dat</strong> and <strong>Grand_validation_set.dat</strong> contain data used in the generation of the magnetosheath magnetic field model and its validation, respectively. Data formats are provided in a separate text file <strong>Data_format.txt</strong>. 2. The file <strong>MS_field_model.for</strong> contains a fortran subroutine for calculating the model magnetosheath magnetic field components.
