Fig. 3.From: Hybrid simulations of proton precipitation patterns onto the upper atmosphere of MarsLongitude-latitude maps of downgoing protons on the outer sphere at r = 3960 km for the B x = 0 simulation. (a) All protons. (b) Solar wind protons. (c) Exospheric protons. (d) Protons with energies >2000 eV. (e) Protons with energies between 400 and 2000 eV. (f) Protons with energies <400 eV.Back to article page
