The authors estimated carbon capacity, carbon saturation, net primary production (NPP), and ecosystem carbon residence time in six US grasslands spanning temperature and precipitation gradients by integrating high temporal resolution carbon pool and flux data with a process-based carbon model. As expected, NPP across grasslands was strongly correlated with mean annual precipitation (MAP), yet carbon residence time was not related to MAP or mean annual temperature (MAT). They link soil temperature, soil moisture, and inherent carbon turnover rates (potentially due to microbial function and tissue quality) as determinants of carbon residence time.
