The GCMD has made it very easy for the public to locate the data sets they desire. All the metadata are accessible via several search interfaces.

Search Options:

• Earth Science Keywords: Search results can be modified Science discipline, geographic location, platform/source, or instrument. Or try the map/date combo data search.
• Full-Text Search: This allows a query on user specified keywords. This can be of use when searching for metadata on specific topics (e.g., El Niño or Global Warming).

A tutorial on the new search functionality is available at http://gcmd.nasa.gov/learn/faqs/search_explanation.html
