We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

SMAP Data Access and Tools
NASA's Soil Moisture Active Passive (SMAP) data products include information about soil moisture and freeze thaw state. Additional Level 4 value-added products are available. Data tools such as Vertex and Earthdata Search enable users to discover and download data.
