NASA's Global Precipitation Measurement mission, or GPM, a joint NASA/JAXA mission, will provide rainfall data on storms and hurricanes like Irene that move out of the tropics. The data will be available when the GPM Core Observatory launches in 2014 and will show in 3D how these storm systems develop and intensify as they move poleward. GPM's Core Observatory, partnered with a constellation of international satellites, will provide a global picture of rain and snow every three hours.
