PostWRF

Visualization and postprocessing of the WRF and ERA5 data

Plot the WRF and ERA5 data, in the same simple way as you run the WRF model!

PostWRF is a bunch of interactive tools, written in NCL and Bash scripts, to visualize and post-process the WRF model outputs (as well as ERA5 and RTTOV data, to some extent).

PostWRF is useful for both the expert and less-experienced users. Students can plot the WRF and ERA5 outputs whithout struggling with coding and syntax errors. Expert users can also carry out common postprocessing tasks in a simple and straightforward way.

Main capabilities:

• WRF Data extraction
• WRF horizontal contour plot
• WRF cross-section plot
• WRF statistical diagrams
• RTTOV input (from WRF) and output data generation
• WRF data conversion to Geotiff
• WRF Skew-T and windrose diagrams
• ERA5 horizontal contour plot
• ERA5 data extraction

Sample visualizations and postprocessing

Installation:

Install NCL on a Linux machine (e.g. Fedora):

sudo dnf install ncl

That's it! Enough for most of the PostWRF's capabilities!

Run PostWRF:

1. git clone git@github.com:anikfal/PostWRF.git
2. cd PostWRF
3. chmod +x postwrf.sh modules/*.sh modules_era/*.sh
4. Copy or link your WRF or ERA5 files in the PostWRF directory
5. ./postwrf.sh
6. Follow the instructions and give relevant information to visualize/postprocess your data
