The rapid intensification of Hurricane Harvey was observed by the radiometer instrument aboard NASA's Soil Moisture Active Passive (SMAP) satellite.
The first year of data from NASA's SMAP mission provides surprising findings that will help in forecasting weather and monitoring crop growth.
A NASA analysis of a 2015 Texas flood is the first to document the full life cycle and impacts of a flood on both land and ocean.
All radiometer data products from NASA’s Soil Moisture Active Passive (SMAP) mission are now available at the National Snow and Ice Data Center.
SMAP is designed to measure the amount of water in the top 5 cm (2 inches) of soil, however it can also be used to estimate the sea surface salinity under normal ocean conditions and may also be used to estimate ocean wind vectors in extreme wind speed events such as tropical cyclones or hurricanes.
