"\n",
"This notebook demonstrates searching for cloud-hosted ICESat-2 data and directly accessing Land Ice Height (ATL06) granules from an Amazon Compute Cloud (EC2) instance using the `earthaccess` package. NASA data \"in the cloud\" are stored in Amazon Web Services (AWS) Simple Storage Service (S3) Buckets. **Direct Access** is an efficient way to work with data stored in an S3 Bucket when you are working in the cloud. Cloud-hosted granules can be opened and loaded into memory without the need to download them first. This allows you take advantage of the scalability and power of cloud computing. \n",

"### **Prerequisites**\n",
"\n",
"1. An Amazon Web Services (AWS) account. You will be accessing data in Amazon Web Services (AWS) Simple Storage Service (S3) buckets. This requires an AWS account, for details on how to set one up see [here](https://nsidc.org/data/user-resources/help-center/nasa-earthdata-cloud-data-access-guide#anchor-1).\n",
"2. An EC2 instance in the us-west-2 region is set up. **NASA cloud-hosted data is in Amazon Region us-west2. So you also need an EC2 instance in the us-west-2 region.** An EC2 instance is a virtual computer that you create to perform processing operations in place of using your own desktop or laptop. Details on how to set up an instance can be found [here](https://nsidc.org/data/user-resources/help-center/nasa-earthdata-cloud-data-access-guide#anchor-1).\n",
"3. An Earthdata Login is required for data access. If you don't have one, you can register for one [here](https://urs.earthdata.nasa.gov/).\n",
"4. A .netrc file, that contains your Earthdata Login credentials, in your home directory. The current recommended practice for authentication is to create a .netrc file in your home directory following [these instructions](https://nsidc.org/support/how/how-do-i-programmatically-request-data-services) (Step 1) and to use the .netrc file for authentication when required for data access during the tutorial.\n",
"5. The *nsidc-tutorials* environment is setup and activated. This [README](https://github.com/nsidc/NSIDC-Data-Tutorials/blob/main/README.md) has setup instructions.\n",
