SMAP NRT Data and Information
The Soil Moisture Active Passive (SMAP) instrument measures the amount of water in the surface soil everywhere on Earth. SMAP is designed to measure soil moisture every 2-3 days. The availability of SMAP data in near real-time (NRT) supports a variety of users and applications, including tropical cyclone imagery display, data assimilation to numerical weather prediction models, agricultural management/forecasting, short term fire forecasts, risk assessment for landslides, and the identification of saturated soil conditions. LANCE generally provides SMAP data within 90 to 120 minutes of satellite observation.
