PACE Spacecraft Housekeeping Telemetry in NetCDF Format

NASA's PACE mission Level-0 engineering and navigation telemetry data includes spacecraft and instrument housekeeping packets, attitude quaternions, angular rates, and orbit position and velocity vectors. The data are archived and distributed by NASA's Ocean Biology Distributed Active Archive Center (OB.DAAC) for community access. The collection is essential for mission operations, calibration, and geolocation of science products from the OCI, HARP2, and SPEXone instruments.

Use Cases

• Calibrate science instrument data from OCI, HARP2, and SPEXone using spacecraft attitude quaternions and timing metadata.
• Perform engineering analysis on spacecraft health and status by monitoring instrument housekeeping packets.
• Improve geolocation accuracy of Earth observation data by processing orbit position and velocity vectors.
• Assess data quality for higher-level science products by analyzing angular rates and navigation telemetry.

Strengths

• Data is Level-0, providing foundational telemetry for mission operations and science processing.
• Includes multiple critical data types: housekeeping packets, attitude quaternions, and orbit vectors.
• Archived by NASA's OB.DAAC for long-term preservation and community access.

Limitations

• Specific row counts, file sizes, and temporal coverage are not provided.
• Data is in NetCDF4 format, which requires specific libraries for access and analysis.
• As housekeeping data, it may contain specialized engineering parameters requiring domain knowledge to interpret fully.
