he Global Change Observation Satellite - Water (GCOM-W), which was launched at 1:39 JST on May 18 (16:39 UTC on May 17), 2012, has achieved its 10-year anniversary today. Both the GCOM-W satellite and on-board instrument, AMSR2, continues operation in healthy condition after designed mission life of 5-year.
We are currently working on preparation for successor mission, the GOSAT-GW satellite, to be launched in JFY 2023. Thank you for your past contributions and we hope your continuous supports to the AMSR series.

    AMSR-E Slow Rotation Data has been released
    The AMSR-E automatically halted its observations and rotation on October 4, 2011 (UTC) due to increased rotation friction. After then NASA and JAXA began to analyze the situation and had been seeking for the way to restart AMSR-E observation. And on December 4, 2012 (UTC,) the AMSR-E restarted its observations and rotation with slow rotation (2 rotations per minute). JAXA completed initial radiometric and geometric correction for slow rotation data, and now AMSR-E Slow Rotation Data is available to public users.
    This data is useful for users who cross-calibrate AMSR-E with other radiometers and who try to research using new feature by slow rotation and so on. This data is not JAXA's standard product. AMSR2 Standard Product is available for general user.
    The detail is described in the following page. -> AMSR-E Slow Rotation Data
