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.
GIBS now has Soil Moisture Active Passive (SMAP) layers available for soil moisture and temperature, snow mass, heterotrophic respiration, and more.
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.
NASA's SMAP team turns raw satellite data into more than a dozen data products for data users around the world.
