ROSETTA-ORBITER 67P ROSINA 2: Comet Gas Measurements from Extension Phase 3

ROSETTA-ORBITER 67P ROSINA 2 EXT3 V2.0 is a CODMAC level 2 science dataset from the Rosetta mission's Extension phase 3 at comet 67P/Churyumov-Gerasimenko. It contains data acquired by the COPS, DFMS, and RTOF sensors between 2016-06-28 and 2016-06-30. The dataset was produced by the National Aeronautics and Space Administration and updated to version 2.0 in March 2026.

Use Cases

• Analyze the composition of comet 67P's coma based on mass spectrometry data.
• Model temporal variations in gas density and pressure based on sensor readings from the described time period.
• Validate and calibrate mass spectrometer instrument models using the provided CODMAC level 2 data.

Strengths

• Data is from the authoritative Rosetta mission, a cornerstone of cometary science.
• Dataset covers a specific three-day observation period (2016-06 28 to 30) during a defined mission phase.
• Version 2.0 indicates curation, with missing files added and corrupted files removed.

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.
