Source code for NMP-Hydro 1.0

NMP-Hydro is a hydrological model based on Noah-MP but coded using the CSharp (C#) language. This model was crafted by creating a framework and accurately translating the original Noah-MP LSM code from WRF-Hydro 3.0, coupled with a Muskingum method-based river routing model(Liu et al., 2023). CSharp, recognized for its modern and object-oriented approach, is widely used for software development across various platforms, particularly on the Windows operating system. NMP-Hydro offers several advantages over the original Noah-MP and WRF-Hydro. Unlike the original version that requires compiling for each computer and predominantly relies on Unix-like systems, NMP-Hydro can seamlessly run on Windows systems supporting the Microsoft Dotnet Framework. The executable files, once compiled, can be easily packaged and distributed to other Windows computers, providing convenience for users less familiar with Unix-like operations. The utilization of the CSharp language facilitates advanced software programs for code visualization and analysis, enhancing user convenience for code reading and modification. The model's design aligns with the input datasets and settings in the 'namelist' file, ensuring compatibility with WRF-Hydro 3.0. Both the translated Noah-MP LSM simulation and the river routing simulation in NMP-Hydro support parallel execution on common personal computers.
