These data cover 1998-12-24T03:47:00Z to 2005-06-09T23:52:00Z. David Hinson 1 Stanford University https://ror.org/00f54p054 2025-02-27 1.0 This is the original version of this collection in PDS4. It was migrated to PDS4 from the PDS3 data set MGS-M-RSS-5-SDP-V1.0. 1998-12-24T03:47:00Z 2005-06-09T23:52:00Z Science Derived MGS Ionospheric Electron Density Profiles Ionosphere Particles Electrons Mars Global Surveyor Mission urn:nasa:pds:context:investigation:mission.mars_global_surveyor collection_to_investigation Mars Global Surveyor Host urn:nasa:pds:context:instrument_host:spacecraft.mgs is_instrument_host Radio Science Subsystem (RSS) Instrument urn:nasa:pds:context:instrument:mgs.rss is_instrument Mars Planet urn:nasa:pds:context:target:planet.mars data_to_target Electrons Density Profile urn:nasa:pds:mgs-rss:data-anc collection_to_ancillary urn:nasa:pds:mgs-rss:data-sha collection_to_data urn:nasa:pds:mgs-rss:document:mgs-rss-eds-sis collection_to_document urn:nasa:pds:mgs-rss:document:data-mgs-rss-desc collection_to_document urn:nasa:pds:mgs-rss:document:errata collection_to_errata 10.1029/1999JE001069 J.D. Twicken, and G.L. Tyler, Initial Results from Radio Occultation Measurements with Mars Global Surveyor, Journal of Geophysical Research, 104, 26997-27012, 1999. Raw samples of DSN receiver output were corrected for observing conditions and converted to bending angle as a function of impact parameter. These results were then inverted to refractive index as a function of radius via an Abel transform. Electron number density was obtained from refractive index using a conversion formula appropriate to the measurement frequency (8423 MHz). 10.1029/2001GL012884 Bougher, S.W., Engel, S., Hinson, D., Forbes, J., Mars Global Surveyor radio science electron density profiles: Neutral atmosphere implications, Geophysical Research Letters, 28(16), pp. 3091-3094.
