Is NWM as good as they say compared to GEOGLOWS?

This project aims to evaluate the effectiveness of the GEOGLOWS in comparison to the National Water Model (NWM) by extracting and analyzing historical simulation data. Utilizing the VPU unit 702 as a focal point, we will extract historical simulations from both GEOGLOWS and NWM and apply a suite of performance metrics, including Mean Error (ME), Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), Nash-Sutcliffe Efficiency (NSE), Kling-Gupta Efficiency (KGE), Pearson's r, and R-squared.

The objective is to assess the goodness of fit for both the global and local models to determine whether the global model (GEOGLOWS) performs comparably to the local model (NWM) in terms of accuracy and reliability in hydrological predictions.
