Modify your WRF input data as easily as running the WRF model!

WRFtailor is a lightweight, namelist-based toolkit written in NCL and Bash.
It allows users to tailor and modify WRF input data (e.g., geo files, emissions data, etc.) based on geographic boundaries or spatial datasets.

For detailed scientific background, see the paper:
📄 Nikfal, A. (2024). WRFtailor: A toolkit for tailoring and modification of WRF input data. Geoscience Data Journal

• Modify WRF input data over an area of interest (AOI) using a shapefile mask
• Modify data using a latitude/longitude bounding box
• Modify values at specific grid points (list of lat/lon coordinates)
• Modify data within the innermost WRF subdomain
• Replace variable values from a GeoTIFF file into WRF input data

Install NCL on your Linux system (example for Fedora):

sudo dnf install ncl

That’s all you need to run all WRFtailor features!

1. Clone the repository

   git clone [email protected]:anikfal/wrftailor.git
   cd wrftailor
   

2. Make scripts executable

   chmod +x wrftailor.sh modules/*.sh
   

3. Copy or link your WRF input files (e.g. geo_em.d01.nc) into the WRFtailor directory

4. Edit and configure your namelist.tailor file

5. Run

   ./wrftailor.sh
   

6. The tailored WRF input data will be generated according to the active sections in namelist.tailor.
