        \cf{N2O} (nitrous oxide) is currently the most important depleter of stratospheric ozone and the third most important radiative forcer among anthropogenic emissions. Its tropospheric chemistry is relatively simple, but other relevant processes are not. Attempts to spatially and temporally quantify \cf{N2O} fluxes have achieved mixed results; however, many researchers agree that agriculture is a major source sector (Fig 1), with N fixation and fertilizer application being important drivers of \cf{N2O} emission. Better characterization of agricultural emissions may facilitate \cf{N2O} mitigation, and may improve understanding of GHG mitigation and adaptation opportunities.

        Efforts to improve estimates of anthropogenic and areal emissions of \cf{N2O} can be characterized using three dimensions: spatial scale, temporal direction (forward or backward) and scale, and depth of insight. A process model makes stronger claims regarding its representation of a system, while a statistical model need only claim quantitative insight. Spatial scale varies from field-scale process modeling and emissions measurement to global emissions inventories (EIs) such as CLM-CN [\citet{k.w._oleson_clm3.5_2007}], EDGAR [\citet{european_commission_joint_research_centre_jrc_emission_2011}], GEIA [\citet{bouwman_uncertainties_1995}], and GFED [\citet{g._r._van_der_werf_global_2010}]. Temporal scales vary from days to years, and can run forward or backward (as with back-trajectory models). Such efforts are more likely to be policy-relevant if conducted at a policy-relevant scale and resolution, and more likely to be skillful where constrained by sufficient observations, i.e., monitoring.

        When analyzed using these three dimensions, current \cf{N2O} modeling efforts fall into three regions, with varying levels of policy relevance and observational constraint. Firstly, strongly empirical, observation-driven field-scale work develops or calibrates models of soil processes which produce and consume \cf{N2O}. This scale suggests resource-intensive, individual- or firm-level policy actions. Secondly, significant effort is devoted to development of EIs for consumption by global-scale climate models. While many entities seek to influence global policies, the ability of these actors to implement and enforce policy tends to be much less than that of regional-scale governments (e.g., EU, US). The utility of this work is also limited by the low temporal frequency, low and irregular spatial coverage, and short history of world-wide continuously-monitored \cf{N2O} records. Thirdly, some recent papers have sought to leverage current US \cf{N2O} monitoring to use inverse modeling techniques to estimate \cf{N2O} EIs for the contiguous US (CONUS), using back-trajectory dispersion models to attribute emissions to potential source regions (Fig 2). Such studies restrict process modeling to meteorology; they mostly model geostatistically. Since their spatial domains correspond to existing regional, state, and national organizations and governments, these efforts should be more policy-relevant.

        There are established models for agricultural biogeochemical processes (notably, EPIC [\citet{texas_agrilife_blackland_research_and_extension_center_epic_2011}], Fig 3) and atmospheric concentrations (notably, CMAQ). Since these can be run at regional scale, such efforts would share the policy relevance of the existing inverse statistical work (and their current relative lack of observational constraint), but could provide the greater depth of system insight (and therefore policy utility) that can derive from successful forward process modeling (as with contemporary conventional air-quality modeling). Particularly, regional process models, if sufficiently skillful, might allow prospective testing of the effects of various agricultural management regimes on \cf{N2O} emissions. The present study seeks to perform forward process modeling of \cf{N2O} over the North American AQMEII domain (AQMEII-NA, Fig 4), focusing on agricultural emissions.
