ROSETTA-ORBITER SREM: Radiation Environment at Comet 67P

NASA's Rosetta spacecraft measured radiation count rates near comet 67P/Churyumov-Gerasimenko using its Standard Radiation Environment Monitor (SREM). The data are CODMAC Level 2 Experiment Data Records from the Medium Term Plan 26 period of the EXTENSION 1 mission phase. It includes count rates per second and their standard deviations.

Use Cases

• Modeling the radiation environment around comet 67P based on measured count rates.
• Analyzing temporal radiation variations during a specific mission phase (MTP026).
• Calibrating or validating other radiation models using SREM instrument standard deviation data.

Strengths

• Data is from a specific, documented mission phase (Medium Term Plan 26, EXTENSION 1).
• Includes standard deviations for the measured count rates, providing error information.
• Produced by NASA, a recognized space agency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
