Hurricane Erin. 3-D computer image of Hurricane Erin on 10th September 2001. This image is composed of data from several instruments. Heat (red) was measured by the Convection and Moisture Experiment (CAMEX) aboard aircraft that flew over and around the hurricane. Rain intensity and distribution (green) was measured by the precipitation radar aboard the Tropical Rainfall Measuring Mission (TRMM) satellite. The clouds (middle top) were measured by infrared detectors aboard the Geostationary Operational Environmental Satellite (GOES)and TRMM. This data was processed by supercomputers at NASA to produce a 3-D animation.
