This webpage, hosted at the MEDOC data center, provides output data from MHD simulations performed using the Wind-Predict model (Réville et al. 2015, Perri et al. 2018), based on the PLUTO code (Mignone et al. 2007). They also include cosmic rays diffusion coefficients parallel and perpendicular to the magnetic field lines, computed using a Python post-processing pipeline.

This data-set includes 5 simulations: 3 of them performed in 2.5D and 2 of them performed in 3D. All simulations correspond to a relaxed state of the wind for a given magnetic field configuration, there is hence no time evolution.

- The 2.5D simulations are theoretical studies of the influence of the magnetic field on the cosmic rays diffusion: the corona is set at 1.5 MK, and only the magnetic field parameters are changed.
- The 3D simulations are set using synoptic maps of a minimum of activity (October 1995) and a maximum of activity (August 1999), already published in another study (Réville & Brun 2017), and run up to 1 AU. Thus we provide 3D maps of the diffusion coefficient of cosmic rays in the inner heliosphere for realistic complex configurations.

The diffusion coefficients are computed using analytical formulae, from Zank et al. 1998 for the parallel diffusion, and from Shalchi et al. 2004 for the perpendicular diffusion.
We have selected 7 rigidities for which we perform the computation, at 1, 10, 100, 445, 10^{3}, 10^{4} and 10^{5} MV, ranging thus from SEPs to GCRs.
