Users may search for data in NSIDC's entire online data catalog, for example, using the Advanced Data Search page, or peruse various product lists on our Web site to locate a specific data set or find data sets that may be of interest. The data itself may be accessed using a variety of methods, including downloading files from our FTP server, ordering data on CD, etc. The catalog page for each data set provides information about the data access methods that are available for it.

NSIDC also provides some specialized data discovery and access methods. These services, databases, and interfaces help you discover, visualize, access, or search-and-order certain data without searching NSIDC's entire online catalog.

Map Services

Atlas of the Cryosphere
Dynamic mapping Web site that allows the visitor to explore the Earth’s frozen regions.

Antarctic Cryosphere Access Portal (A-CAP) (Beta version)
A-CAP is a geo-visualization tool for NSIDC's Antarctic Glaciological Data Center (AGDC) data and other Antarctic-wide parameters.

GLIMS Glacier Database
Unique inventory of critical information about glaciers, with both a Web mapping service and a text search interface.

MODIS Mosaic of Antarctica (MOA) Image Map
Web-based map server that can create manually-selected JPEG images of the Antarctic continent and surrounding islands.

Virtual Globes
Data-based images overlaid on an interactive virtual globe using Google Earth™.

Photograph & Information Databases

Glacier Photograph Collection
Searchable database of glacier photographs, including special collections of glacier photograph pairs.

World Glacier Inventory
Searchable inventory of glacier names, number, location, and other information.

Search-and-Order Interfaces

Warehouse Inventory Search Tool (WIST)
Search for and order data from NSIDC and other Distributed Active Archive Centers (DAACs). Allows FTP and media distribution, as well as subsetting capabilities. Browse images are also available via the WIST.

Data Pool
The Data Pool provides direct FTP access to NSIDC's complete archive of AMSR-E, ICESat/GLAS, MODIS, and NISE products. A simple Web search interface helps you quickly locate data of interest.

Search 'N Order Web Interface (SNOWI)
Search for and order data from NSIDC and other Distributed Active Archive Centers (DAACs). Unlike the WIST, SNOWI only searches DAAC EOS data and NISE data (plus MOD02, MOD09, and MOD35), and it does not offer subsetting.

MODIS Interactive Subsetting Tool (MIST)
Search for and receive certain Version 5 (V005) MODIS data products over the Greenland Climate Network (GC-Net) and the International Arctic Systems for Observing the Atmosphere (IASOA) stations. MIST also provides limited online analysis capabilities that include generating time series and scatter plots.

Discovery, Access, and Delivery of Data for IPY (DADDI)
DADDI provides facetted data search and access to Arctic data held by a growing number of data centers. All IPY data registered in the IPY Metadata Portal at the Global Change Master Directory are also searchable.
