Nitrogen (N) is a key limiting nutrient in terrestrial ecosystems, but there remain critical gaps in our ability to predict and model controls on soil N cycling. The National Ecological Observatory Network (NEON) is producing continental scale, standardized measurements of soil nitrogen pools and transformation rates, which can help fill these gaps. Yet even for a network using uniform protocols, there are some methodological/analytical challenges in generating this open dataset.
This EDI data package contains a derived dataset that addresses these challenges in order to facility community use. In addition, it contains the R code used to evaluate sources of variation within the NEON sampling design and compare measured net N mineralization to simulated fluxes from the Community Earth System Model 2 (CESM2).
This dataset is part of a larger project which aims to provide a robust estimate of soil organic carbon (SOC) for the United States to help combat climate change and ensure food and nutritional security. By using multivariate quantitative methods and machine learning, site-based measurements across the National Ecological Observatory Network will be upscaled to provide SOC regional maps for the CONUS. The project also offers training opportunities for students and teachers, and enables the diagnosis of terrestrial C cycle processes using historical CMIP6 model runs.
