Abstract

Recent increases in anthropogenic inputs of nitrogen to air, land and water media pose a growing threat to human health and ecosystems. Modeling of air-surface N flux is one area in need of improvement. Implementation of a linked air quality and cropland management system is described, and a tool to facilitate estimation of fertilizer input information required by the air quality model is presented. Preliminary evaluation of the coupled system against observations indicates improved wet deposition estimates.
