How to convert data for Geogrid

Back to the WRF-SFIRE user guide.

This wiki page explains how to transform geotiff files to geogrid using convert_geotiff script in wrfxpy.

Get Anaconda3 distribution

Download and install the Python 3 Anaconda Python distribution for your platform. We recommend an installation into the user's home directory.

wget https://repo.continuum.io/archive/Anaconda3-2019.10-Linux-x86_64.sh
chmod +x Anaconda3-2019.10-Linux-x86_64.sh
./Anaconda3-2019.10-Linux-x86_64.sh

Add your environment (~/.custom.csh) the following line

setenv PROJ_LIB "$HOME/anaconda3/share/proj"

or if you are using bash to ~/.profile or ~/.bashrc

export PROJ_LIB="$HOME/anaconda3/share/proj"

Install environment

Create a python environment for gdal compatibility. Shortly this is going to be the environment for wrfxpy installation.

conda create -n wrfxpy python=3 gdal netcdf4 pyproj paramiko dill scikit-learn h5py pandas psutil proj4
conda activate wrfxpy
conda install -c conda-forge simplekml pygrib f90nml pyhdf xmltodict basemap
pip install MesoPy python-cmr

Note that conda and pip are package managers available in the Anaconda Python distribution.

Get wrfxpy repository

Get repository wrfxpy and checkout to convert_geotiff branch. Shortly, it is going to be available in the master branch.

git clone https://github.com/openwfm/wrfxpy
git checkout convert_geotiff

Run convert_geotiff.sh
