The GPM core observatory satellite had a good view of tropical cyclone Alcide on November 6, 2018 at 11:09 a.m. EST (1609 UTC). At that time Alcide had maximum sustained winds of about 35 knots (40.3 mph). GPM's Microwave Imager (GMI) and GPM's Dual-Frequency Precipitation Radar (DPR) instruments collected data that showed the location and intensity of precipitation within Alcide. GPM's GMI indicated that strong convective storms northwest of Alcide's center of circulation were dropping rain at a rate of more than 44 mm (1.73 inches) per hour.  GPM's radar (DPR Ku Band) probed Alcide in a swath through the eastern side of the tropical cyclone. Those data revealed the locations of precipitation within feeder bands spiraling into the southeastern side of the intensifying tropical cyclone.

At NASA's Goddard Space Flight Center in Greenbelt, Maryland, a 3-D animation was created from the data that showed a simulated flyby above Tropical Cyclone Alcide. Measurements of the relative heights of precipitation within tropical cyclone Alcide were made possible using GPM's radar data (DPR Ku Band). DPR's Ku Band radar enables three dimensional measurements of precipitation within a 152 mile (245 km) wide swath. The heights of precipitation over a larger area were estimated by blending measurements from GPM's radar (DPR Ku band) with heights based on the Meteosat satellite's infrared temperatures. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.
