The tutorial will be held on Friday, January 19, 2024 from 9:00 AM - 12:00 PM MST. We will have office hourse to answer any questions on Friday, January 19, 2024 from 1:00 PM - 2:00 PM MST.
The tutorial content here is written as Jupyter Notebooks. You can either browse rendered versions of these notebooks on this website, or execute the code examples interactively following [our guidelines](## ⌨️ Getting set up).
This tutorial is open to non-UCAR staff. If you don’t have access to the HPC systems, you may not be able to follow along with the second part of the tutorial. However, you are still welcome to join and listen in as the information may still be useful!

Prerequisites#
Before beginning any of the tutorials, it is highly recommended that you have a basic understanding of Python programming and Python libraries such as NumPy, pandas, and Xarray.
⌨️ Getting set up#
This tutorial is open to non-UCAR staff. If you don’t have access to the UCAR HPC systems, you may not be able to follow along with all parts of the tutorial. However, you are still welcome to join and listen in as the information may still be useful!
NCAR JupyterHub#
This is the preferred way to interact with this tutorial. Users with access to Casper can run the notebooks interactively, and will be able to save their work and pull in new updates. To connect to NCAR JupyterHub, please open this link in a web browser: https://jupyterhub.hpc.ucar.edu/
Once you logged in, start new a server using Casper Login and hit “Launch Server”.
Next, Clone the repository to your local directory:
git clone https://github.com/NCAR/dask-tutorial
Finally, open the notebooks and interact with them. Make sure to choose the NPL 2024a kernel.
Using Binder#
Users without access to the NCAR/UCAR Casper cluster can still use binder to run through the first notebook . 
Local installation instructions#
Users without access to the NCAR/UCAR Casper cluster can run through the first notebook on their machine.
To run the notebooks locally:
First clone this repository to your local machine via:
git clone https://github.com/NCAR/Xarray-Dask-ESDS-2024
If you do not already have the conda package manager installed, please follow the instructions here.
Now, create a conda environment:
Navigate to the Xarray-Dask-ESDS-2024/ directory and create a new conda environment with the required
packages via:
cd Xarray-Dask-ESDS-2024
conda env update --file environment.yml
This will create a new conda environment named “xarray-dask-esds-2024”.
Next, activate the environment:
conda activate xarray-dask-esds-2024
Finally, launch JupyterLab with:
jupyter lab
