Search Rules

The keyword search capability on the GES DISC Web Portal supports the following search query syntax:

General Rules:

Searching on multiple words

To search on multiple optional keywords use spaces to separate search terms.
Example, AIRS OMI TRMM, searches for data sets matching "AIRS" OR "OMI" OR "TRMM"

To search for datasets that contain ALL required keywords, enclose the words in double quotes.
Example, "GPM precipitation", returns datasets that contain "GPM" AND "precipitation"

To search for required and optional keywords use a combination of quoted and non-quoted keywords.
Example, "atmospheric radiation" clouds aerosols, searches for all data sets containing "atmospheric" AND "radiation" AND ("clouds" OR "aerosols")

Excluding words from search results

To exclude specific keywords from a search, prefix the word with a hyphen "-".
Example, AIRS -clouds -aerosols, searches for all data sets matching AIRS and will not include any that include "clouds" OR "aerosols"

Example, "trmm microwave imager" -clouds, searches for all data sets containing "trmm" AND "microwave" AND "imager" AND will not include any that include "clouds"

Navigation Features

Refine By

Use Refine By to narrow your search result by filtering on various facets such as Science Disciplines, Measurements, Spatial and Temporal Resolution. The list of available facet groupings and facets that appear under "Refine By" depends on the keywords entered into the search box. To apply facet filtering simply click the checkbox next to the facet and the search results will dynamically update. A count is displayed alongside each facet to indicate the number of search results. To aid you in finding filter criteria, the facet groups can be sorted either by alphabetical order (ascending or descending) or by result count (ascending or descending).
