On the morning of Oct. 8, 2018, the NASA Soil Moisture Active Passive (SMAP) Radiometer got a snapshot of Hurricane Michael, which has intensified to a Category 2 hurricane over the warm waters of the Gulf of Mexico. The radiance acquired by the SMAP L-band Microwave Radiometer can see through clouds and rains, and is sensitive to the extreme ocean surface winds under a tropical storm or hurricane. Areas in red represent higher wind speeds; areas in blue have lower wind speeds.
