Its main purpose is to contribute to the global change issues, such as global warming, ozone depletion and carbon cycle.It has 5 main sensors; global imager, advanced microwave scanning radiometer, sea winds, polarization and directionality of the Earth's reflectances, and improved Lim atmospheric spectrometer-II. In this mission, collaboration with exiting international research projects is heavily emphasized such as global energy and water cycle experiment, and climate variability and predictability of the world climate research program, International Geosphere-Biosphere Program, global ocean observing systems and global climate observing system. Its present status will be concisely summarized.
