MOSART Nitrogen Routing Model v1.0.0

This software release contains the MOSART nitrate-nitrogen routing scheme used in Felfelani et al. (2026). The implementation explicitly simulates riverine nitrate-nitrogen concentrations by solving the one-dimensionaladvection-dispersion-reaction equation. This is the version used to generate the results reported for the Great Lakes Basin. The corresponding CTSM framework used to configure and run this software is archived separately at [DOI: 10.5281/zenodo.21725400]. 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).
