NASA Earthdata Cloud

This article covers frequently asked questions about the NASA NSIDC DAAC's Earthdata cloud migration project and what it means to data users.

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.

NASA Earthdata provides options for accessing NSIDC DAAC data through both HTTPS (https://…) and S3 (s3://…) URLs. Understanding which URL type to use can significantly improve your data access workflow and efficiency.

This article shows how to download NSIDC DAAC data from NASA Earthdata Cloud to your computer using three tools: wget and curl—popular command-line utilities for downloading files—and Data Downloader, a Python-based command-line tool developed by the Physical Oceanography Distributed Active Archi

NASA’s NSIDC DAAC offers two easy, browser-based methods to download cloud-hosted data — no coding required. This guide covers both:Earthdata SearchHTTPS File System (CMR Virtual Directory)PrerequisitesBefore getting started, ensure you have:

earthaccess is a Python library that simplifies authentication, search, and download of data from NASA's Earthdata systems.

This quickstart guide will walk you through the essential steps to start using the Harmony API to request subsetted files with specific spatial and temporal filters applied for select data sets.

Data subscriptions provide automatic notifications and updates when new data becomes available. This guide covers two methods for setting up subscriptions: the Earthdata Search web interface and the command-line PO.DAAC Data Subscriber tool. 

The NASA Earthdata Cloud is the NASA cloud-based archive of Earth observations. It is hosted by Amazon Web Services (AWS). Learn how to find and access NSIDC DAAC data directly in the cloud.
