IMAGE EUV M2: Plasmasphere Plasma Distribution Maps

IMAGE satellite extreme ultraviolet (EUV) imager data detects resonantly scattered solar photons at 30.4 nm wavelength. The database provides global snapshots of spatial and temporal plasma distributions throughout the plasmasphere. Data has been mapped to the equator using a method from Gallagher et al. (2005) and used to create an automated plasmapause extraction technique.

Use Cases

• Mapping plasmasphere plasma density distributions based on EUV photon detection
• Automated extraction of the plasmapause position based on maximum gradient search
• Analyzing temporal evolution of the plasmasphere based on global snapshot database
• Studying magnetic local time (MLT) dependent plasmapause variations based on the extraction technique

Strengths

• Data originates from the NASA IMAGE satellite mission.
• The plasmapause extraction technique is automated and described in Katus et al. (2015).
• Data has been mapped to the equator using a published method (Gallagher et al., 2005).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include BIN and HTML, which may require specialized tools for processing.
