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. Read about the Web Unification Project

Soil Moisture/Water Content Data Access and Tools

NASA has soil moisture and water content datasets that help researchers characterize the condition of soil around the world. Access a range of data and data tools such as the Soil Moisture Visualizer, Crop Condition and Soil Moisture Analytics (Crop-CASMA), and AppEEARS to make the most of soil moisture data.

Featured Observation Method: SMAP

The Soil Moisture Active-Passive (SMAP) platform is a satellite that measures the surface moisture and freeze-thaw state of soil around the world approximately every three days. SMAP data contributes to understanding regional water cycles, ecosystem productivity, and natural processes involving water, energy, and carbon. SMAP's high-resolution data are helpful for weather, flood, and drought forecasting, and predicting agricultural productivity.

16 New SMAP Products Now Available

GIBS now has Soil Moisture Active Passive (SMAP) layers available for soil moisture and temperature, snow mass, heterotrophic respiration, and more.
