How to use the OPeNDAP / DODS Server in Ferret.

The following explains the steps of loading data servered by OPeNDAP using Ferret.

Select a dataset on a OPeNDAP server:

• Earth Simulator Center (authentication required)
• IPRC only(authentication required)
• Public data

Get the URL by clicking on "info" for the dataset of your interest, say NLOM on the "Public data" server, which looks like this:

OPeNDAP Server (GDS) - top level - public_data - NLOM


OPeNDAP Server (GDS) - directory for /public_data/NLOM : 4 entries

---


1: nlom_ssh: NLOM SSH   info  dds  das

The OPeNDAP URL is near the top of the "info" page and looks like this:

OPeNDAP URL:	http://apdrc.soest.hawaii.edu/dods/public_data/NLOM/nlom_ssh
Authenticated:	http://username:passwd@apdrc.soest.hawaii.edu/dods/public_data/NLOM/nlom_ssh

(Please note: Ferret v5.81 does not work with password authentication)

Start Ferret:

ferret

Load data using the URL and proceed as you normally would:

yes? SET DATA "http://apdrc.soest.hawaii.edu/dods/public_data/NLOM/nlom_ssh"
