Getting ESMF and ESMFPy Running on Ubuntu: A (Hopefully) Painless Guide

So, you’re diving into Earth science or ocean modeling and need to get ESMF (Earth System Modeling Framework) and its Python buddy, ESMFPy, up and running on your Ubuntu machine? Awesome! ESMF is a seriously powerful tool for linking together different models, and ESMFPy lets you wrangle it all from the comfort of Python, which, let’s be honest, is where most of the cool data analysis happens these days.
