Over half of N₂O is emitted via ebullitions in a shallow eutrophic lake

This dataset comprises dissolved N₂O concentrations, diffusive fluxes, ebullitive fluxes, and associated water quality parameters from Lake Ulansuhai, a shallow eutrophic lake. Sampling was conducted monthly from May to October 2021 across seven sites. The current version provides complete spatiotemporal coverage and includes newly added sediment data.
