ROSETTA-ORBITER 67P SREM 2: Radiation Count Rates at Comet 67P

Radiation count rates and standard deviations measured by the Standard Radiation Environment Monitor (SREM) on the Rosetta spacecraft during the Medium Term Plan 35 period of the EXTENSION 3 mission phase. The data targets comet 67P/Churyumov-Gerasimenko and is provided as CODMAC Level 2 Experiment Data Records. The dataset is published by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Modeling the radiation environment around comet 67P/Churyumov-Gerasimenko based on measured count rates.
• Analyzing radiation flux variability during the EXTENSION 3 mission phase based on time-series data.
• Calibrating or validating space radiation models using the provided standard deviation metrics.
• Studying spacecraft instrument performance for the Standard Radiation Environment Monitor (SREM).

Strengths

• Data is from a specific mission phase (EXTENSION 3, Medium Term Plan 35), providing temporal context.
• Includes standard deviations alongside count rates, offering error estimates.
• Data is classified as CODMAC Level 2, which suggests a defined level of processing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count, file formats, and sample data are unknown, which may limit suitability assessment.
