Step-by-Step Guide: Installing ESMF and ESMFPy in Ubuntu with gfortran, gcc, and Python for Earth Science and Ocean Models

Introduction to the ESMF and ESMFPy

ESMF (Earth System Modeling Framework) is a powerful software infrastructure developed at the National Center for Atmospheric Research (NCAR) that enables the construction and execution of coupled Earth system models. ESMF provides a set of libraries and tools that facilitate the development, coordination, and execution of complex, multi-component models used in oceanography, atmospheric science, and other Earth science disciplines. ESMF supports a wide range of platforms and programming languages, including Fortran, C, and Python.

ESMFPy is the Python interface to ESMF, allowing users to take advantage of ESMF’s capabilities within the Python programming language. With ESMFPy, you can develop and run ESMF-based models, perform data regridding and interpolation, and access a wealth of geospatial data and functionality for geoscience applications.

In this article, we will walk you through the process of installing ESMF and ESMFPy on Ubuntu using gfortran, gcc, and Python. By following these steps, you will be able to set up a development environment to harness the power of ESMF and ESMFPy for your ocean modeling and geoscience projects.

Step 1: Install the dependencies

Before installing ESMF and ESMFPy, we need to make sure that all the necessary dependencies are installed on our Ubuntu system. ESMF depends on Fortran and C compilers, so we will start by installing the gfortran and gcc packages. Open a terminal and run the following command to install these dependencies:

How to install ESMF and ESMFPy in Ubuntu using gfortran, gcc, python?

To install ESMF and ESMFPy in Ubuntu using gfortran, gcc, and Python, you can follow the steps below:

1. Install the required dependencies

Before installing ESMF and ESMFPy, make sure you have the necessary dependencies installed. Open a terminal and run the following command:

sudo apt-get install gfortran gcc python3-dev

2. Download ESMF

Visit the ESMF website (https://www.earthsystemcog.org/projects/esmf/) and download the latest version of ESMF source code or use a specific version you require.

3. Extract the ESMF source code

Extract the downloaded ESMF source code archive to a directory of your choice.

tar -xzf esmf.tar.gz

4. Configure and build ESMF

Change to the ESMF source code directory and run the following commands:

cd esmf
export ESMF_DIR=$(pwd)
make

5. Install ESMF

After the build process completes, run the following command to install ESMF:

make install

6. Install ESMFPy

To install ESMFPy, you can use the Python package manager pip. Run the following command:

pip install ESMF

7. Verify the installation

You can verify the installation by importing the ESMFPy module in a Python script or an interactive Python session:

python
import ESMF

If the import statement executes without errors, it indicates that ESMF and ESMFPy have been successfully installed in your Ubuntu system.
