## Prerequisites

The tutorial can be run with the guest Earthdata Login that is in `earthdatalogin`. However, if you will be using the NASA Earthdata portal more regularly, please register for an Earthdata Login account. Please <https://urs.earthdata.nasa.gov> to register and manage your Earthdata Login account. This account is free to create and only takes a moment to set up.

See the [1-earthdatalogin](1-earthdatalogin.html) tutorial for set-up if you are running the tutorial locally.
