Model code modifications and model outputs-Improvements in the Land and Crop Modeling over Flooded Rice Fields by Incorporating the Shallow Paddy Water

We incorporated the shallow paddy surface water layer into the Noah-MP land surface model to improve its performance of surface heat fluxes over flooded rice paddies. Field measurements from two crop sites, i.e., SAITO (early rice) and SAGA (late rice), were used to initialize and evaluate the modified Noah-MP model. Additionally, we investigated the roles of some key parameters in the land and crop modeling. The related model code modifications as well as model outputs were included in this dataset.

Note that, all numerical experiments in this study were conducted at the field scale using the offline version of Noah-MP (Niu et al., 2011) running within the High-Resolution Land Data Assimilation System (HRLDAS v3.9; Chen et al., 2007). Please refer to the official HRLDAS/Noah-MP unified Github repository (https://github.com/NCAR/hrldas-release) for the original model codes.
