Polar Mesoscale Cyclones (PMC) tracking algorithm

• cmake
• netCDF with Fortran enabled
• Fortran-90 compiler

The easiest way to install all the dependencies is to use conda. Once you have downloaded conda (Miniconda is recommended), create an isolated environment by running

conda create -n pmctrack -c conda-forge cmake libgfortran fortran-compiler netcdf-fortran

This should fetch all the necessary libraries which then can be used for compilation.

Then activate the environment

conda activate pmctrack

and proceed to installation.

Run the script

./INSTALL.sh

All options are stored in CMakeLists.txt file. You can add shortcut for your platform.

./track.x [settings.conf]

To accompany the tracking algorithm itself, a software package for postprocessing and analysis has been written in Python: octant.
