Nitrous oxide emissions under different corn field managements in the United States
… Colorado were modeled using the process-based Denitrification Decomposition (DNDC) model, which is used to predict trace gas emissions from agriculture based on field and climate conditions. The DNDC model was evaluated for predicting N2O emissions from corn cropping systems in the United …

Biosphere-atmosphere exchange of ammonia from a fertilized corn canopy in Central Illinois
… were also used to evaluate closure with DeNitrification DeComposition (DNDC) model predictions of NH3 flux. A new method to address practical issues of evaluating closure was developed to account for flux footprints extending outside the measurement site and differences in measurement and …

Impact of spatial and temporal distribution of ammonia emissions from chemical fertilizer usage on predictions of air quality in the Midwest United States
… of emissions based on the biogeochemical Denitrification Decomposition (DNDC) model. In ISS, NH3 emissions from chemical fertilizer usage are gridded at 4 km x 4 km and 12 km x 12 km resolutions, using detailed crop maps and crop specific nitrogen loading data. Daily variations in NH3 …
