==WRFx: Requirements and environment==

===Install Anaconda distribution===
Download and install the Python 3 [https://repo.continuum.io/archive conda] distribution for your platform.
We recommend an installation into the users' home directory. For example,
wget <nowiki>https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh</nowiki>
chmod +x Miniconda3-latest-Linux-x86_64.sh
./Miniconda3-latest-Linux-x86_64.sh
The installation may instruct you to exit and log in again.

On a shared system, you may have a system-wide Python distribution with conda already installed, perhaps as a module, try module avail.

===Install necessary packages===
The currently preferred process is to have conda find the versions for you:
conda create -n wrfx python=3.8
conda activate wrfx
conda install -c conda-forge gdal
conda install -c conda-forge netcdf4 h5py pyhdf pygrib f90nml lxml simplekml pytz pandas scipy
conda install -c conda-forge basemap paramiko dill psutil flask wgrib2
pip install MesoPy python-cmr shapely==2

On Linux x86-64, you can also use versions specified in a yml file:
wget https://demo.openwfm.org/web/wrfx/wrfx.yml
conda env create --name wrfx --file wrfx.yml
Note: The versions listed in the yml file may not be available on platforms other than Linux x86-64 (most common), or may just not work as package repositories evolve.

===Set environment===
Every time before using WRFx, make the packages available by
conda activate wrfx

==WRFx: wrfxpy==

WRF-SFIRE forecasting and data assimilation in python using an HPC environment.

===wrfxpy: Installation===
====Clone github repository====
Clone wrfxpy repository
git clone <nowiki>https://github.com/openwfm/wrfxpy</nowiki>
Change to the directory where the wrfxpy repository has been created
cd wrfxpy

====General configuration====
An etc/conf.json file must be created with the keys discussed below. A template file etc/conf.json.initial is provided as a starting point.

cd wrfxpy
cp etc/conf.json.initial etc/conf.json

Configure the queuing system, system directories, WPS/WRF-SFIRE locations, and workspace locations by editing the following keys in etc/conf.json:
"sys_install_path": "/path/to/wrfxpy"
"wget" : "/path/to/wget"

Note that the rest of the paths are not used by FMDA, so you can leave defaults or remove them. To find the default wget,
which wget

====Tokens configuration====

When running wrfxpy, sometimes the data needs to be accessed and downloaded using a specific token created for the user. For instance, in the case of running the Fuel Moisture Model, one needs a token from a valid [https://mesowest.utah.edu/ MesoWest] user to download data automatically. All of these can be specified with the creation of the file etc/tokens.json from the template etc/tokens.json.initial containing:

{
"mesowest" : "token-from-synopticdata.com"
}

So, if any of the previous capabilities are required, create a token from the specific page, do

cp etc/tokens.json.initial etc/tokens.json

and edit the file to include your previously created token.

For running the fuel moisture model, a new MesoWest user can be created in [https://developers.synopticdata.com/ MesoWest New User]. Then, the token can be acquired and replaced in the etc/tokens.json file. Also, the user can specify a list of tokens to use.
