MAVEN: Mars Atmosphere In-situ Observations at 4-Second Cadence

In-situ observations from NASA's MAVEN spacecraft orbiting Mars, containing calibrated data from multiple instruments measuring particles and fields. The data bundle includes measurements from the Neutral Gas and Ion Mass Spectrometer and the Particles and Fields package, all averaged to a uniform 4-second cadence. Data are provided in physical units and include derived ephemeris information.

Use Cases

• Modeling atmospheric escape processes based on neutral gas and ion composition data.
• Analyzing solar wind interaction with Mars based on magnetic field and solar wind particle measurements.
• Studying ionospheric dynamics based on Langmuir probe and waves instrument data.
• Correlating spacecraft position with environmental measurements using the included ephemeris data.

Strengths

• Data are fully calibrated and provided in physical units.
• Multiple instrument datasets are bundled and synchronized to a uniform 4-second time cadence.
• Ephemeris data are derived using established SPICE libraries and kernels.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data are provided in BIN format, which may require specialized tools for access.
