SMAP (Soil Moisture Active Passive)

SMAP (Soil Moisture Active Passive) is a satellite mission that measures soil moisture levels globally. It uses two technologies: active radar and passive radiometry, to provide accurate readings regardless of weather or cloud cover. This data helps scientists and farmers understand how much water is in the soil, which is crucial for agriculture, weather forecasting, and managing water resources. By monitoring soil moisture, SMAP supports better decision-making related to drought prevention, flood management, and climate studies, ultimately contributing to sustainable land and water management worldwide.
