COWVR, TEMPEST Capture Vital Data on Hurricane Franklin

A pair of weather instruments built at NASA's Jet Propulsion Laboratory in Southern California captured images of Hurricane Franklin as the Category 4 storm moved off the East Coast of the United States on Aug. 29, 2023. COWVR (short for Compact Ocean Wind Vector Radiometer) and TEMPEST (Temporal Experiment for Storms and Tropical Systems) observe the planet's atmosphere and surface from aboard the International Space Station, which passed in low Earth orbit over the storm at about 9:58 a.m. EDT. This image combines microwave emissions measurements from both COWVR and TEMPEST. White sections indicate the presence of clouds. Green portions indicate rain. Yellow, red, and black indicate where air and water vapor were moving most vigorously. Franklin's center is seen about 700 miles (1,127 kilometers) east of Jacksonville, Florida, over the Atlantic Ocean. https://photojournal.jpl.nasa.gov/catalog/PIA25870
