Fig. 6: Electric field distribution in the Martian ionosphere.
From: Two distinct current systems in the ionosphere of Mars
The \({E}_{r}\), \({E}_{\theta }\), and \({E}_{\varphi }\) component of the ionospheric electric field at 150 km altitude in the Mars-Solar-Electric (MSE) (a–c) and Mars-Solar-Orbital (MSO) (d–f) coordinates, respectively. Arrows represent the amplitude and direction of the electric field in the horizontal plane, with length represented logarithmically. The dashed lines in each panel represent the noon and terminator. The statistical altitude is labeled in the top right corner of each panel. Gray arrows illustrating the electric field pattern on the dayside have been added to the middle panels (b, e). Source data are provided as a Source Data file.
