This repository is supplementary to the manuscript "Sun, Y., Oleson, K.W., He, C., & Zheng, Z. (2025). Advancing CLMU for regional climate simulations through WRF coupling: intercomparison with NOAH–SLUCM".
The objectives of this project are:
- Develop an urban-focused workflow of WRF-CLMU coupling for regional urban climate simulations;
- Comparatively evaluate two single-layer urban canopy models (i.e., CLMU and NOAH-SLUCM) in an atmosphere-land coupled mode;
- Examine model sensitivity to urban parameters.
- The scripts listed below are used to describe input data and generate plots.
