IMF clock angle proxy: orbital averaged magnetic field data from MAVEN in Martian magnetosheath

The By and Bz components can be used as IMF clock angle proxy (IMF direction in MSO y-z plane). See the publication by Dong et al. 2019 for details: Dong, Y., Fang, X., Brain, D. A., Hurley, D. M., Halekas, J. S., Espley, J. R., et al. (2019). Magnetic field in the Martian magnetosheath and the application as an IMF clock angle proxy. Journal of Geophysical Research: Space Physics, 124, 4295–4313. https://doi.org/10.1029/2019JA026522 Formats: IDL save file and ASCII file Data descirption: Time span: Nov 11 2014 - Oct 31 2025 Time: averaged unix time of MAVEN in magnetosheath of each s/c orbit # of data points: # of data points (time resolution: 4s) taken in magnetosheath of each s/c orbit. Suggest using only # of data points >150 (i.e. duration > 10 min) Bx, By, Bz in MSO coordinate system Sheath magnetic field is not recorded when there is upstream IMF observation in the same s/c orbit. In such cases, please use the actual IMF data.
