Short summary
Scarce reliable greenhouse‑gas observations plague inland Antarctica. The low‑power (<350 W) CRUX‑1.0 integrates four subsystems for simultaneous CO₂‑O₃ monitoring. Its one‑month Taishan Station test shows stable performance, with post‑calibration CV  (coefficient of variation) < 5.6 %. Measured mixing ratios exhibit good comparability with South Pole Station data. Capable of unattended operation, CRUX‑1.0 is promising for data‑scarce polar inland deployment.
