The Global Geocryological Data System

The Frozen Ground Data Center (FGDC) serves as a central node of the IPA Global Geocryological Data (GGD) system. The GGD is an internationally distributed system linking investigators and data centers around the world. The FGDC facilitates the operation of the GGD by collecting and distributing information (metadata) describing permafrost and frozen ground related data. Many of the products listed here are available directly through the FGDC; some are held by other institutions. For those data sets held by other institutions, NSIDC provides the original metadata for the data set, and asks users to contact the Principal Investigator for access to the data.

Submit Frozen Ground Data to NSIDC

We urge investigators to contribute their frozen ground data and metadata to the GGD. All contributors will be fully credited, and we encourage users of these data to formally cite data contributors.

Access Frozen Ground Data Sets at NSIDC

You can either search for Frozen Ground data in our product catalog or browse the catalog.
