How do I access data using OPeNDAP?

Data can be programmatically accessed using NSIDC’s OPeNDAP Hyrax server, allowing you to reformat and subset data based on parameter and array index. For more information on OPeNDAP, including supported data sets and known issues, please see our OPeNDAP documentation:

*Please note that changes will occur to OPeNDAP access in the future in order to accommodate NASA Earthdata Login. If you would like to register to receive updates to NSIDC’s OPeNDAP service, please email us at
