� GCOM-W1 and AMSR2 are in good shape.� GCOM-W1 “SHIZUKU”◦ Launched on May 18, 2012 (JST).◦ Joined A-Train constellation.◦ Completed the initial checkout phase on August 10, 2012.
� AMSR2◦ Started continuous observation from July 3, 2012 (JST).◦ Calibration and validation activities are ongoing.◦ Preliminary products were already made available to PIs and
collaborating agencies.◦ Product release to public will be 8-months and 12-months after
launch for brightness temperatures and geophysical parameters.◦ GCOM Data Providing Service at http://gcom-w1.jaxa.jp.
� Will participate in GPM constellation.
