MGS Mars Magnetometer: Calibrated High-Resolution Data from 1997-1999

Calibrated high time resolution magnetic field measurements from the Mars Global Surveyor spacecraft's MAG instrument. NASA collected this data during the premapping and aerobraking phases from September 12, 1997, to March 8, 1999. The data is expressed in both payload and Sun-State coordinate systems.

Use Cases

• Modeling Mars's crustal magnetic field based on high-resolution magnetometer readings.
• Analyzing solar wind interactions with the Martian atmosphere based on Sun-State coordinate data.
• Studying temporal variations in the Martian magnetic environment during the aerobraking mission phase.
• Calibrating or validating other planetary magnetometer datasets based on the described coordinate systems.

Strengths

• Data is explicitly calibrated, which suggests a processed and validated state.
• Covers a specific 18-month time range from 1997-09-12 to 1999-03 08.
• Provides high time resolution detail word data, likely suitable for fine-grained analysis.
• Originates from the authoritative NASA organization.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment for large-scale processing.
• The license is listed as 'other-license-specified', requiring careful review before use.
