ESGF_RSS - ESGF/esgf.github.io GitHub Wiki

ESGF provides extremely powerful notification services based on the popular RSS technology. By subscribing to an ESGF RSS feed, a user can keep track of newly published datasets, or of new versions of already published datasets, at many levels: all datasets from a specific ESGF node, all datasets across the ESGF federation, or datasets that match a specific search criteria: a project, an experiment, a variable, etc.

RSS feeds are simply web sites (a.k.a. URLs) that deliver their content in XML format. Nowadays, many applications exist that are capable of displaying the content of an RSS feed in a human-readable fashion (as opposed to display the raw XML): from all major browsers (Firefox, Chrome, Safari) to specialized applications for the desktop and portable devices (for example, NetNewsWire or the iPhone app _ Free RSS Reader _ ).

Currently, ESGF offers the RSS feeds listed below. To display each feed, simply cut-and-paste the URL into your browser or your chosen application, and bookmark it to subscribe to it. Any time the feed is updated, the browser or application will display the number of new items in the feed. The most important of these feeds are also reachable from any ESGF Node home page, by clicking on the RSS icon.

Dataset-level feeds list the most recently updated datasets, and are hyperlinked both to the THREDDS catalogs, and to the file-level feeds (see below). At each ESGF node, the following feeds are available:

• http://<esgf.host.name>/esg-search/feed/nodes.rss

  • This feed is the same for all ESGF nodes, and includes all most recent datasets in the entire ESGF federation.
  • Example: http://esg-datanode.jpl.nasa.gov/esg-search/feed/nodes.rss

• http://<esgf.host.name>/esg-search/feed/node.rss

  • This feed is node specific, and includes all the most recent datasets from that node only
  • Example: http://esg-datanode.jpl.nasa.gov/esg-search/feed/node.rss

• http://<esgf.host.name>/esg-search/feed/<facet_name>/<facet_value>.rss

  • This feed includes all the most recent datasets that match a given search category (a.k.a. facet) name and value, across the whole federation. It is the same at all nodes.

  • Example: http://esg-datanode.jpl.nasa.gov/esg-search/feed/cf_standard_name/air_temperature.rss includes all most recent datasets that contain _ Air Temperature _ , across all sites.

  • Example: http://esg-datanode.jpl.nasa.gov/esg-search/feed/project/CMIP5.rss includes all most recent observational datasets for CMIP5, across all sites.

These feeds include _ all _ files (up to 1000) for a given dataset, no matter where it is located across the federation. They hyperlink to the THREDDS catalog for that dataset, and contain all the download access URLs for each file. These feeds always show the latest version of the requested dataset, no matter how long ago it was published.

• http://<esgf.host.name>/esg-search/feed/dataset/<dataset_id>.rss

  • Example: http://esg-datanode.jpl.nasa.gov/esg-search/feed/dataset/obs4MIPs.NASA-JPL.AIRS.mon.v1|esg-datanode.jpl.nasa.gov.rss includes all files for the dataset with id _ obs4MIPs.NASA-JPL.AIRS.mon _ .
