Basic tutorial for ESMPy Python package

ESMPy is the Python interface for the Earth System Modelling Framework (ESMF) regridding utility. You can find out more here. This repository contains a brief tutorial on how you can use this package to do some common regridding tasks. These examples use data from numerical weather prediction models as well as surface stations, all which are included. Take a look at the Jupyter Notebook and see how to use the package. Happy regridding!

Current examples available:

• grid to grid (bilinear)
• grid to grid (first-order conservative)
• points to grid
• grid to points
• parallel grid to grid via MPI (bilinear)

Plots in this tutorial are created using cartopy. Previous versions were created using basemap. A branch containing the old basemap version is around for now, but will be deleted at some point.

Replace NPROCS with the number of processes you want to use and be sure mpi4py is installed.

mpirun -n NPROCS python esmpy_mpi_example.py

If you have specific questions about the ESMPy software or its development, you will be much better served by getting into contact with the actual ESMPy developers (I am not one, just a happy user) at [email protected].
