• The Operation IceBridge Portal is being decommissioned in June 2025 as NSIDC DAAC migrates to NASA Earthdata Cloud. On June 11, 2025, new data orders will no longer be accepted. Previous orders will remain accessible through the "Orders" tab until June 25, when the portal will be permanently removed. Learn more about alternative options and support here.

  • The NSIDC DAAC is retiring access to its legacy, on-premises data archive and transitioning to the NASA Earthdata Cloud as the primary data archive. View planned retirement dates at https://nsidc.org/data/user-resources/help-center/when-will-legacy-premises-archive-be-retired.

Overview

This data set contains simplified, or thinned, flight lines from NASA Operation IceBridge Greenland, Arctic, Antarctic, and Alaska missions. The thinning was performed using a Python library called Shapely. The full resolution flight line data were collected as part of Operation IceBridge funded aircraft survey campaigns. The corresponding flight reports can be found in the IceBridge L1B Flight Reports (IPFLR1B) data set.

General Questions & FAQs

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is migrating its primary data access from its legacy, on-premises archive to the NASA Earthdata Cloud.

How to Articles

Many NSIDC DAAC data sets can be accessed using NSIDC DAAC's Data Access Tool. This tool provides the ability to search and filter data with spatial and temporal constraints using a map-based interface.Users have the option to:
The NSIDC Data Map Services Application Programming Interface (API) provides HTTP URLs for requesting geo-registered map images from NSIDC's geospatial database. A WMS request defines the geographic layer(s) and area of interest to be processed.
All data from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) is directly accessible through our HTTPS file system using Wget or curl. This article provides basic command line instructions for accessing data using this method.
