SPRING 2026 PAYLOAD DATA

Spring 2026 Mission — Sensor Telemetry

Geiger counter & atmospheric sensor data collected during high-altitude balloon flight (peak ~83,600 ft)

FULL-FLIGHT VIEW Charts span launch to landing. Ascent uses payload sensor telemetry; descent continuity is aligned to APRS full-flight timing/altitude profile so the entire mission is visible in one scientific view.

MASTER TELEMETRIST PASS

Data Quality Review & Limitations

A transparent QA pass intended for technical audiences, with explicit weaknesses and mitigation notes. Public charts use a processed visualization dataset.

Observed Data Flaws

Negative altitude values are present in early records, indicating offset or baseline calibration effects near launch.
Payload dataset uses sample index instead of explicit timestamp in the published telemetry JSON.
Particle channels have low dynamic spread (small integer ranges), suggesting quantization and limited vertical sensitivity.
No propagated uncertainty bands are included in the current visualizations.
Cross-sensor synchronization metadata is not embedded in this release package.

Mitigation & Interpretation Notes

Use relative altitude trends and phase transitions (ascent, peak, descent) rather than absolute pre-launch offsets.
Interpret PM channels comparatively across altitude bands instead of as high-precision absolute concentration values.
Read CO₂, temperature, and humidity together for atmospheric context, not as isolated indicators.
Prefer raw-table verification below before citing outliers in reports.
For publication-quality claims, add calibration metadata and uncertainty model in future releases.

Data Visibility Policy

Raw Geiger row-level telemetry is intentionally kept private for mission controls and technical review workflows. This page presents processed, downsampled visual analytics and derived full-flight continuity for public scientific communication.
