The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) will add SnowEx 2017 data sets from the NASA SnowEx collection to NASA Earthdata Cloud on 2 April 2025. Subsequent SnowEx campaigns (SnowEx 2020, SnowEx 2021, and SnowEx 2023) will also be added to Earthdata Cloud in the coming weeks. Earthdata Cloud is NASA’s archive of Earth observations, hosted in Amazon Web Services (AWS). The Earthdata Cloud HTTPS data access URL will be available from each data set landing page using the HTTPS File System link under Data Access & Tools after the publication date.
The URL for access to the legacy HTTPS File System will be removed from the data set landing page when the data are added to Earthdata Cloud. However, you can continue to find legacy HTTPS URLs in the Programmatic Data Access Guide at https://nsidc.org/data/user-resources/help-center/programmatic-data-access-guide.
The NSIDC DAAC User Services Office currently supports users with direct data download from the Earthdata Cloud HTTPS and with basic access to our AWS Simple Storage Service (S3) buckets. For more details on the access options, please see the following help resources:
