nsidc.org OpenSearch API
Overview
The OpenSearch Application Programming Interface (API) provides a simple way to discover and access NSIDC's data holdings that are hosted through Searchlight. We support two levels of the OpenSearch API: Data Set and Granule. Use the Data Set OpenSearch API to search for data sets that fulfill your search criteria, or use the Granule OpenSearch API to search for data meeting your search criteria for a particular data set.
To help you create the OpenSearch queries, choose one of the following options:
If you are familiar with OpenSearch and don't need help setting up the Data Set OpenSearch API, see our Data Set Description Document. If you are not familiar with OpenSearch and would like help, follow the directions given below.
To use the Data Set OpenSearch API, paste the following URL into the URL field of a browser, adding the appropriate values for the parameters listed in Table 1 to define your query string. The query string can contain all or any combination of the parameters listed in Table 1.
Note: The parameters loc= and bbox= can not be used together in a query. You must use only one of them per query. Also, the query string is case sensitive and the search is not a free text search, but a very structured search. The ? in the query string separates the URL from the parameters, and the & separates the variables.

Example Query Strings
Polygon Geometry Query String
The following is an example of a query string for a Polygon Geometry query using the example variables listed in Table 1:

Example Results for a Polygon Geometry Query
Figure 1 is an example of the results received from the Polygon Geometry query listed above. This particular query returned only one data set, the DMSP SSM/I-SSMIS Pathfinder Daily EASE-Grid Brightness Temperatures data set.

Granule OpenSearch APIs
Currently, we only support seven data sets at the granule level. Refer to Table 2. The Long Name in Table 2 is a link to the data set documentation. You can use the data set documentation to find pertinent information for your data query such as temporal coverage and spatial coverage to name just a few.
If you are familiar with OpenSearch and don't need help using the seven APIs, see our Description Documents listed in Table 3. The Long Name in Table 3 is a link to the Description Document for that data set.
If you are not familiar with OpenSearch and would like help, follow the directions given below.
Choose one of the following data sets that you would like to do an OpenSearch on:

IceBridge Mission Flight Reports (IFLTRPT)
There are two ways to find the flight report you are looking for when using the Granule OpenSearch API for the IceBridge Mission Flight Reports. You can either enter appropriate values for the parameters listed in Table 10 to define your query string, or you can use one parameter called Measurment in your query string. By using the Measurement parameter, the user receives a full listing of all the flight reports currently stored at NSIDC. From this listing, the user can drill-down to find a specific flight report by clicking on a given data record.
Choose one of the following:
Using the Measurement Parameter to Find a Flight Report
- Paste the following URL into the URL field of a browser.

Note: The parameters loc= and bbox= can not be used together in a query. You must use only one of them per query. Also, the query string is case sensitive and the search is not a free text search, but a very structured search.
