摘要:Abstract The uptake of nitrous oxide (N 2 O) occurs at the surface of the earth both in terrestrial and aquatic systems. This uptake is usually neglected in N 2 O budget studies. In this article, we discuss the likeliness of N 2 O uptake in different systems. These systems include soils as well as groundwater systems, riparian zones and surface waters. We address the possible consequences of ignoring surface sinks for N 2 O in global budgets as well as in national emission inventories. Our estimated surface sink is relatively small compared to the estimates of the present-day global emissions. Neglecting a possible surface sink of N 2 O may, therefore, not have major consequences for atmospheric budget studies on the global scale. However, locally, N 2 O uptake may be considerable. For countries with large areas prone to N 2 O uptake, neglecting this sink in national budgets may have important consequences.
