 ## Step 3: Prepare a list of granules (files) to download
 
-Now the only step that remains is to get a list of URLs to pass to *wget* or *curl* for downloading. There's a lot of ways to do this -- even more so for ECCO datasets data because the files/datasets follow well-structured naming conventions -- but we will rely on Earthdata Search to do this from the browser for the sake of simplicity.

 **1. Find the collection/dataset of interest in Earthdata Search.**
 
 Start from this [complete list of ECCO collections](https://search.earthdata.nasa.gov/portal/podaac-cloud/search?fpj=ECCO) in Earthdata Search, and refine the results until you see your dataset of interest.
 
 In this example we will download all of the granules for the collection [ECCO Version 4 Release 4 (V4r4) monthly sea surface height on a 0.5 degree lat-lon grid](https://search.earthdata.nasa.gov/portal/podaac-cloud/search/granules?p=C1990404799-POCLOUD).

 **2. Choose your collection, then click the green *Download All* button on the next page.**

 That will add all the granules in the collection to your "shopping cart" and then redirect you straight there and present you with the available options for customizing the data prior to download.  In this example we ignore the other download options those because they are in active development.

 **3. Click *Download Data* to get your list of download urls (bottom-left, another green button)**
 
 The *Download Data* button takes you to one final page that provides the list of urls from which to download the files matching your search parameters and any customization options that you selected in the steps that followed. This page will be retained in your User History in case you need to return to it later.

+There are several ways that you could get the list of urls into a text file that's accessible from Jupyter or your local shell. I simply clicked the **Save** button in my browser and downloaded them as a text file. (You could also copy them into a new notebook cell and write them to a file like we did with the ```netrc``` file above.).
