Proton cyclotron waves upstream from Mars: Observations from Mars Global Surveyor

► We study the properties of the PCW's present upstream from Mars. ► We analyze the frequency, propagation and polarization properties of these waves. ► We show statistical analyses of their amplitude and spatial distribution. ► We perform a statistical analysis of the Solar Wind IMF cone angle associated with them. ► We study the implications of our results and compare with recent studies.
