Dataset for "Currents in the Martian Ionosphere: Cases Without Strong Crustal Magnetic Fields"

# Ionospheric_Currents_Figures_Data This archive contains compact figure-ready data products for the manuscript Figures 1-7. ## Files - `Ionospheric_Currents_Figures_Data.mat`: MATLAB v7.3 file containing `ZenodoFigureData`.- `README.md`: this note. ## MATLAB Use ```matlabS = load('Ionospheric_Currents_Figures_Data.mat');D = S.ZenodoFigureData;plot(D.Figure2.cases(1).derived_current.J_E_uA_m2, ... D.Figure2.cases(1).derived_current.altitude_km);xlabel('J_E (uA/m^2)'); ylabel('Altitude (km)');``` ## Contents - `Figure1`: DD2-period IMF clock-angle proxy and proton proxy.- `Figure2`: four case magnetic-field observations, smooth-spline fitted magnetic fields, and derived currents.- `Figure3`: schematic note only; no data product is needed.- `Figure4`: neutral winds, Pedersen/Hall conductivities, and dynamo currents. Both `JP` and `JH` are included.- `Figure5`: raw Figure 5 source `.mat` contents, including MHD simulation profiles and associated source files, without extra processing.- `Figure6`: NGIMS and MCD neutral-wind results.- `Figure7`: four case profiles and the reference MHD profile used for comparison. ## Unit Conventions Time is Unix seconds; altitude is km; magnetic field is nT; plotted currents are uA/m^2 unless a field name states A/m^2; conductivity is S/m; wind is m/s; densities are #/cm^3 unless stated otherwise; temperature is K. `Figure7.cases.case_profiles.sigmaP_source_code_S_m` preserves the Pedersen conductivity calculation used in `Compare_MHD.m` for Figure 7.
