“…We estimated forest NO emissions (5.9 Tg N year −1 ) that were higher than previous reports because we used a larger forest area (5638 Mha) and emission per unit area (1.04 kg N ha −1 year −1 ) to reach our estimates (Table S4) (Yan et al, 2005). Our emission per unit area was lower than the 1.34 kg N ha −1 year −1 estimated by a recent meta‐analysis (Table S4) (Huang et al, 2022). The discrepancy is likely due to the fact that the meta‐analysis primarily included in‐situ observations from tropical and temperate regions but few observations from cold regions (Huang et al, 2022).…”

“…Soil water conditions are commonly recognized as important drivers of soil NO emissions, including soil moisture, water input, and soil WFPS (Huang et al, 2022; Liu et al, 2017; Pärn et al, 2018; Schindlbacher et al, 2004). Our analysis showed that water input significantly affected soil NO emissions, exhibiting a positive correlation with soil NO emissions (Figures 2 and 3).…”

Soils are a major source of global nitric oxide (NO) emissions. However, estimates of soil NO emissions have large uncertainties due to limited observations and multifactorial impacts. Here, we mapped global soil NO emissions, integrating 1356 in‐situ NO observations from globally distributed sites with high‐resolution climate, soil, and management practice data. We then calculated global and national total NO budgets and revealed the contributions of cropland, grassland, and forest to global soil NO emissions at the national level. The results showed that soil NO emissions were explained mainly by N input, water input and soil pH. Total above‐soil NO emissions of the three vegetation cover types were 9.4 Tg N year−1 in 2014, including 5.9 Tg N year−1 (1.04, 95% confidence interval [95% CI]: 0.09–1.99 kg N ha−1 year−1) emitted from forest, 1.7 Tg N year−1 (0.68, 95% CI: 0.10–1.26 kg N ha−1 year−1) from grassland, and 1.8 Tg N year−1 (0.98, 95% CI: 0.42–1.53 kg N ha−1 year−1) from cropland. Soil NO emissions in approximately 57% of 213 countries surveyed were dominated by forests. Our results provide updated inventories of global and national soil NO emissions based on robust data‐driven models. These estimates are critical to guiding the mitigation of soil NO emissions and can be used in combination with biogeochemical models.

“…Huang et al. (2022) found S NOx to peak at 37% WFPS during the growing season in a chamber study in Northeastern China. Schindlbacher and Zechmeister‐Boltenstern (2004) investigated S NOx at various forested sites in Europe and found the soil moisture optimum for S NOx to range from 15%–65% WFPS, depending on the location.…”

“…In a S NOx chamber study in Southern California, U.S., Oikawa et al (2015) identified peak S NOx at an optimum of approximately 30% VSM, or approximately 60% WFPS, depending on the assumed soil porosity. Huang et al (2022) found S NOx to peak at 37% WFPS during the growing season in a chamber study in Northeastern China. Schindlbacher and Zechmeister-Boltenstern (2004) investigated S NOx at various forested sites in Europe and found the soil moisture optimum for S NOx to range from 15%-65% WFPS, depending on the location.…”

Nitrogen oxides (NOx = NO + NO 2 ) are direct air pollutants responsible for a range of negative health impacts and increased mortality (Forastiere & Peters, 2021). Beyond its direct health impacts, NOx also plays a crucial role in the formation of harmful secondary air pollutants, including ozone and particulate matter (Duncan et al., 2010;Hauglustaine et al., 2014). In the United States (U.S), fossil fuel combustion represents the largest source of NOx emissions, although fossil NOx emissions have been decreasing over the past two decades (Jiang et al., 2022). This decline in fossil NOx emissions has highlighted the increasing importance of other NOx sources, including soils, to the overall NOx budget (Geddes et al., 2022;Miyazaki et al., 2020). While soil NOx emissions (S NOx ) occur naturally in most soils, the most intense emissions are anthropogenic and occur in cropland regions where nitrogen-rich fertilizers are applied to soils (Almaraz et al., 2018). These anthropogenically-influenced emissions have local impacts (Lu et al., 2021). Biogenic S NOx form the bulk of background NOx concentrations, particularly in rural regions (Silvern et al., 2019). Given its growing importance to atmospheric NOx, improved understanding of processes controlling S NOx is imperative for improving our understanding of the role of NOx in the formation of secondary air pollutants and its influence on air quality (Geddes et al., 2022;Qu et al., 2021).
