M3 electron density layer in the dayside ionosphere of Mars: Analysis of MAVEN ROSE observations

We investigate the characteristics of the topside M3 layer in the Martian dayside electron density profiles obtained from the Radio Occultation Science Experiment (ROSE) onboard the MAVEN spacecraft. M3 layer is a local enhancement in the electron density above the prominent ionospheric M2 peak. ROS...

Description
Summary:We investigate the characteristics of the topside M3 layer in the Martian dayside electron density profiles obtained from the Radio Occultation Science Experiment (ROSE) onboard the MAVEN spacecraft. M3 layer is a local enhancement in the electron density above the prominent ionospheric M2 peak. ROSE measurements have a wider latitudinal and solar zenith angle (SZA) coverage as compared to the spacecraft observations used by previous studies for characterizing the M3 layer. We analyzed 179 dayside (SZA
