The Global Precipitation Measurement (GPM) Core Observatory flew over Hurricane Arthur five times between July 1 and July 5, 2014. Arthur is the first tropical cyclone of the 2014 Atlantic hurricane season.<br /><br />GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency. The Core Observatory was launched Feb. 27 from Japan and began its prime mission on May 29, just in time for the hurricane season.<br /><br />The five GPM passes over Arthur are the first time a precipitation-measuring satellite has been able to follow a hurricane through its full life cycle with high-resolution measurements of rain and ice. In the July 3 image, Arthur was just off the coast of South Carolina. GPM data showed that the hurricane was asymmetrical, with spiral arms, called rain bands, on the eastern side of the storm but not on the western side.<br /><br />To read more and see the data animation- please go to:<br /><br />http://www.nasa.gov/content/goddard/nasa-jaxas-new-precipitation-satellite-sees-first-atlantic-hurricane/#.U-kNsFYrubE
