Short summary

Unmanned aircraft could provide a cost-effective way to close gaps in the observation of the carbon cycle, provided that small yet accurate analysers are available. We have developed a COmpact Carbon dioxide analyser for Airborne Platforms (COCAP). During validation of its CO₂ measurements in simulated and real flights we found a measurement error of 1.2 μmol mol⁻¹ or better with no indication of bias. COCAP is a self-contained package that has proven well suited for operation on board UASs.
