BARREL 1D X-ray Spectrometer Fast Time Resolution Bremsstrahlung Data

Antarctic and Arctic stratospheric balloon campaigns collected this data. It contains four channels of fast time resolution (50 ms) Bremsstrahlung X-ray spectra from 0 MeV to 1.5 MeV, measured by NASA's BARREL mission. The data was gathered during campaigns from 2013 to 2016 to study electron precipitation from Earth's radiation belts.

Use Cases

• Study electron losses from Earth's Radiation Belts based on the mission's stated purpose
• Characterize spatial scales of relativistic electron precipitation based on the description
• Analyze temporal variations of electron precipitation based on the fast time resolution (50 ms) data
• Correlate balloon X-ray measurements with in-situ plasma wave and particle data based on the comprehensive measurement context

Strengths

• Fast time resolution of 50 milliseconds per channel
• Four separate spectral channels (FSPC1-FSPC4) covering an energy range from 0 MeV to 1.5 MeV
• Data collected from over 50 stratospheric balloon launches across four campaigns

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
