Evaluating Regional N2O Emissions and Drivers Using Airborne Observations
Abstract
Global nitrous oxide continues to rise driven by increasing emissions from human activities. Emissions from applied fertilizer are the dominant anthropogenic component. Understanding emissions from applied fertilizer (how emissions relate to fertilizer practices and climate variables) will prove essential for understanding future N2O impacts and to guide possible mitigation. In particular, regional scales (10-100km) play a critical role and have proven challenging to evaluate. Here I will discuss how we use airborne N2O measurements to quantify emissions from point sources and on regional scales, and how we can link observed emissions to specific drivers. I will further evaluate what spatial scales we can resolve, and whether these airborne measurement approaches can be used to evaluate emissions from neighboring croplands with different practices.
