How to visualize WRF-Fire output in VAPOR

Prerequistes

A working installation of WRF-Fire, possibly on another computer or a cluster.
Visualization computer with a decent graphics card, 3 button mouse.
Download and install VAPOR
- Read Getting started with VAPOR first.
- On a Mac, run the installation package, then add to your path /Applications/VAPOR.app/Contents/MacOS
- Do the exercises in the first few pages of the VAPOR quick start guide to learn the basics of the controls.
- VAPOR can be used remotely over a special version of VNC to avoid transferring huge datasets to your visualization computer.

Change in namelist.input the line with history_interval to the desired frame interval in seconds, for example history_interval_s=1. Make sure frames_per_outfile is large enough so that only one wrfout file is produced.
Run WRF-Fire. Pictures below are from the "hill" ideal run in WRF-Fire.
If the visualization computer is different from the computer where you run WRF-Fire, transfer the wrfout file to the visualization computer
Convert the wrfout file for use with VAPOR: run from the command line
- wrfvdfcreate yourwrfoutfile yourwdffile.vdf
- wrf2vdf wrf-fire.vdf yourwdffile.vdf
Start VAPOR by clicking on its icon or vaporgui from the command line
In the GUI, click "Data" on the top menu bar, then "load dataset in the current session", and navigate to the yourwdffile.vdf you have just created. In the black right panel, you should see an empty wireframe box from the top.
Click the "Flow" tab, check the box "Instance 1", click "OK" on a warning about flow lines below zero. Select "Refinement" 2. You should see a picture like this:

Click the "Animation" tab and move the slider to the middle. The flowlines should move a little.
Click the "2D" tab, check "Instance 1", select "Refinement" 2, and 2D variable GRNHFX, check "Apply color and opacity to terrain surface", and push the "Fit data" button at the bottom.
Rotate the image with a mouse to see something like this:
