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.

Featured Permafrost Observation Method: SMAP
The Soil Moisture Active-Passive (SMAP) platform measures surface soil moisture and freeze-thaw state. These direct measurements can be analyzed to learn more about permafrost distributions.
Near real-time soil moisture data from the Soil Moisture Active Passive (SMAP) L-Band Radiometer instrument are available through Land, Atmosphere Near real-time Capability for Earth observation (LANCE).
NASA's SMAP team turns raw satellite data into more than a dozen data products for data users around the world.

Remote sensing data's drought-indicating parameters are essential to manage the impact of water scarcities and minimize drought losses.
This webinar will compare sea surface salinity data collected by the Aquarius and SMAP missions. We will showcase data visualization and data access tools available through NASA's Physical Oceanography Distributed Active Archive Center.
