MHD simulations for MHD wave reflection in coronal solar wind

Data and file format description The dataset contains plasma number density outputs from a one-dimensional magnetohydrodynamic (MHD) simulation. The original simulation results are stored as a time-ordered sequence of NetCDF (.nc) files, with each file representing one simulation snapshot. The variables used in the post-processing procedure are plasma mass density (rho), spatial grid spacing (dx), and physical simulation time (RealT). These variables are stored as floating-point numerical data. Two virtual observation locations are selected along the simulation domain. The first location corresponds to grid index 129. The second location is approximately 4,000 km farther along the spatial direction, and its grid index is calculated using the spatial grid spacing. Assuming a fully ionized hydrogen plasma, the plasma mass density is converted to particle number density by dividing it by the proton mass, taken as 1.6726219e-27 kg. A fixed integration length of 2.0e8 m is then applied to estimate the column-integrated electron content. The resulting values are divided by 1.0e16 and expressed in total electron content units (TECU), where 1 TECU corresponds to 1.0e16 electrons per square metre. The processed results are stored in a MATLAB-compatible file named TEC.mat. The file contains three numerical arrays: tec1: TEC time series at the first observation location tec2: TEC time series at the second observation location time: physical simulation times corresponding to the TEC measurements The conversion from mass density to electron content assumes a quasi-neutral, singly ionized, pure-hydrogen plasma. Under this assumption, the electron number density is approximately equal to the proton number density.
