+# Laser Altimetry Applications for a Changing World: Working with ICESat-2 Sea Ice Data
+
+## Overview
+This directory contains a notebook demonstrating how to work with ICESat-2 Sea Ice Data using `earthaccess`, `xarray` and `matplotlib`.
+
+The demo was presented at the NASA Earthdata Webinar held on Wednesday, 6 August, 2025.
+
+## Learning Outcomes
+
+1. How to search for ICESat-2 data sets (collections) using `earthaccess`.
+2. How to search for data files using a time range and spatial extent.
+3. How to open an ATL07 and ATL10 using `xarray`
+4. How to make a simple plot of ATL07 data using `matplotlib`
+
+## Setup
+
+You will need at least version 2024.10.1 of `xarray` and version 0.14.0 of `earthaccess` for this tutorial.  We recommend creating a virtual environment using the `environment.yml` file in the environment folder using `mamba` or `conda`.
+
+```
+mamba env update -f environment/environment.yml
+```
+or
+```
+conda env update -f environment/environment.yml
+```
+
+This will create an virtual environment called `nsidc-tutorial-icesat2-apps`.
+
+To activate the environment.
+
+```
+mamba activate nsidc-tutorial-icesat2-apps
+```
+or
+```
+conda activate nsidc-tutorial-icesat2-apps
+```
+
+You can now launch Jupyter Lab and navigate to `working_with_icesat2_sea_ice_data.ipynb`.
