Short summary

Nitrous oxide (N₂O), a potent greenhouse gas, is understudied in coastal zones. We present N₂O concentrations and air–sea fluxes from the Balearic coast (2018–2023). Concentrations varied slightly across sites, with areas acting as weak sources or being near equilibrium. Temperature was the main driver of seasonal changes. These findings improve our understanding of coastal N₂O emissions.
