BARREL 2E Data Processing Unit (HKPG) Analog Housekeeping Voltage, Temperature, Current, a

BARREL 2E Data Processing Unit housekeeping data provides voltage, temperature, current, and payload status values recorded every 40 seconds. The BARREL Mission was a NASA Living with a Star project involving over 50 stratospheric balloon launches from Antarctica (2013-2014) and Sweden (2015-2016) to study electron precipitation from Earth's radiation belts. This Level 2 dataset contains analog sensor data based on the nominal payload layout.

Use Cases

• Monitor payload health and instrument status based on housekeeping voltage and current readings.
• Analyze environmental conditions during balloon flights using temperature data.
• Correlate balloon-based X-ray measurements with in-situ satellite data from the Van Allen Probes mission.
• Study the spatial and temporal scale of electron precipitation events using time-series data from a constellation of balloons.

Strengths

• Data collected from over 50 balloon flights across four campaigns spanning 2013 to 2016.
• Time-series data with a regular 40-second sampling interval for housekeeping parameters.
• Mission was part of a coordinated NASA program with the Van Allen Probes and other ground-based instruments.

Limitations

• Analog sensor data is based on a nominal layout; some payload-specific differences may not be reflected.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
