| 요약 | Nitrous oxide (N2O) and methane (CH4) are important long-lived greenhouse gases. However, evidence has been found that CH 4 and N2O emissions from the US Corn Belt are much larger than budgeted for in the most up-to-date emission inventories, im |
| 요약 | Therefore, this dissertation sought to: 1) quantify importance of direct versus indirect N2O emissions, and explore their seasonality and regional budgets |
| 요약 | We compared in-situ measurements of N2O from the University of Minnesota tall tower site with a time-inverted transport model and a scale factor Bayesian inverse (SFBI) method. Our analysis suggested an upward adjustment of the emission factor o |
| 요약 | With respect to CH4, our analysis revealed that the anthropogenic source (7.8 +/-1.6 Tg CH4 yr-1) was 1.5 times greater than accounted for in the EPA inventory. Most prominently livestock and oil/gas sources were underestimated by 1.8- and 1.3-f |
| 요약 | Our findings suggest that indirect N2O and anthropogenic CH4 emissions within the Corn Belt Region need to be upward-adjusted in inventory updates. Further, our model predictions indicate large N2O mitigation potential in the lower Midwest regio |
