The Global Change Observation Mission (GCOM) consists of two polar orbiting satellite observing systems, GCOM-W (Water) and GCOM-C (Climate), and three generations to achieve global and long-term monitoring of the Earth. GCOM-W1, which is the first satellite of the GCOM-W series, was launched from the Tanegashima Space Center on May 18, 2012 (Japan Standard Time), and moved to the regular observation operation on August 10, 2012 (JST) after the early orbit checkout had been completed. The early initiation of the Advanced Microwave Scanning Radiometer-2 (AMSR2) on GCOM-W1 observation was highly desired since the Advanced Microwave Scanning Radiometer for the Earth Observing System (AMSR-E) had halted its observation in October 2011 due to the increase of antenna rotation torque. The calibration activity of AMSR2 is going on toward the data release of Level-1 product scheduled in the beginning of 2013. The initial checkout of the ground segment, including systems for receiving, processing, archiving, and distributing the GCOM-W1 data, is also completed successfully. At-launch retrieval algorithms were used for the checkout. These algorithms will be validated and updated through calibration and validation activities. Public data release is scheduled one year after launch for geophysical parameters. Standard products will be available via online, free of charge, from the GCOM-W1 data providing service system. The AMSR-E products are already available from the same system. © (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
