ARTEMIS P1: Magnetic Field and Plasma Data Near the Moon

ARTEMIS P1 field-plasma merged data contains magnetic field and plasma ion measurements from the THEMIS-B spacecraft instruments during its near-moon phase after September 1, 2010. The data set was created at NASA's GSFC/Space Physics Data Facility as part of the LunaSOX effort, merging ESA and FGM instrument data. It includes geocentric and selenocentric spacecraft position data derived from SSCWeb.

Use Cases

• Modeling the lunar magnetic environment based on high-resolution magnetic field data.
• Analyzing plasma ion dynamics near the Moon based on plasma ion measurements.
• Studying spacecraft position relative to Earth and Moon using the added geocentric and selenocentric coordinates.
• Correlating magnetic field fluctuations with plasma behavior using the merged instrument data.

Strengths

• Data resolution is specified at 96-second and 384-second intervals.
• Data originates from NASA's THEMIS-B spacecraft instruments and was processed by the GSFC/Space Physics Data Facility.
• Records include spacecraft position data from two coordinate systems (geocentric and selenocentric).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data coverage is described as 'several mutually exclusive, contiguous hours during most days', suggesting incomplete daily coverage.
