Short summary
Soil emissions of nitrous oxide (N2O), a potent greenhouse gas, are highly variable over space and time. Existing approaches for automated N2O emission measurements are costly and often incompatible with flooded soils. We describe and validate a robust and low-cost apparatus for replicated measurement of soil N2O emissions at subdaily resolution over large spatial gradients (> 100 m). High-frequency measurements are critical for constraining and mitigating the soil N2O source.
