Data files are displayed in a table at the top of the dataset landing page, below the citation (Figure 2). Here you can view the name, file type, and size of each datafile and select which ones you would like to download. Alternatively, you can select the download icon at the top to download all files as a zip file.

Download Large Data on Tier 2

Tier 2 data files are accessible for download via the external link table at the top of the dataset metadata landing page (Figure 3). In this table, there are two options to choose from when downloading Tier 2 data: HTTP or Globus.

Tier 2 (HTTP):

The HTTP access link can be used to download individual files directly from your browser. For those familiar with command line tools, it can be used to download data in bulk.

1. Scroll down to the "External Links to Data and Metadata" table and select the URL next to the external link titled "ESS-DIVE Tier 2 (HTTP)"; this will redirect you to the Tier 2 data page (Figure 4).

2. All data files will be located in the data/ folder.

3. You can browse and download files individually as needed by selecting the file.

If you are familiar with command line tools, you can initiate a bulk download with wget or curl by pulling all the files in the data folder. The manifest-md5.txt contains a list of all files with MD5 sums.

Tier 2 (Globus):

The Globus access link can be used to download multiple files at once from your browser. Additionally, you can choose to download the files locally or to transfer them to an existing cloud storage service, if applicable. To download files locally, it is necessary to install Globus Connect Personal.

1. Scroll down to the "External Links to Data and Metadata" table (Figure 3) and select the URL next to the external link titled "ESS-DIVE Tier 2 (Globus)"; this will direct you to Globus.

2. You will be prompted to login to access the data on Globus (Figure 5). If you are new to Globus, see ESS-DIVE's instructions to Create a Globus Account.

   1. Individual file download: At this point, you have the option to select individual files for download. Continue reading to download multiple files at once or entire folders.

3. If you are new to Globus, see ESS-DIVE's instructions to Install Globus Connect Personal on your desktop. Return to the File Manager in your browser (Figure 5) when you have finished setup.

4. In the Globus File Manager, use the panel toggle in the top right to change your view to two panels (Figure 6).

5. In the empty panel, select the “Collection” search bar and navigate to the “Your Collections” tab (Figure 7). Then select your desktop collection. Alternatively, you can select any other existing cloud endpoint you may have on Globus.

6. Now you’re ready to download (i.e. transfer) the data. On your desktop panel, navigate to where you want to download the files. On the dataset panel, select some or all files to download then either use the “Sync transfer...” button or the "Start" button to start the transfer (Figure 8). You can also drag the selected files to your desktop.

7. This will start a transfer job and you will see a green popup window on your screen confirming that the transfer has started (Figure 9).

In many cases the transfer is quick, but if your transfer is taking a while, use the link from this popup window to check in on the status of the transfer or look in the Activity tab. You will know that the transfer is complete when Globus sends you a confirmation email.
