CTSM–MOSART Nitrogen Routing Model v1.0.0

This software release contains the modified Community Terrestrial Systems Model framework used in Felfelani et al. (2026) to simulate riverine nitrate-nitrogen fate and transport. The release couples CLM5 with the MOSART nitrogen-routing implementation and pins the exact MOSART source-code commit used in the study through Externals.cfg. The corresponding MOSART nitrogen-routing source-code release is archived separately at [DOI: 10.5281/zenodo.21725387]. Felfelani, F., Pokhrel, Y., Phanikumar, M. S., and Lawrence, D. M. (2026), Riverine Nitrate Fate and Transport in the Great Lakes Basin using the Community Land Model. Journal of Advances in Modeling Earth Systems (JAMES).
