AMSR Viewer was released.
AMSR Earth Environment Viewer (AMSR Viewer) is a display system for a global earth observation data observed by the Advanced Microwave Scanning Radiometer (AMSR) series consisting of GCOM-W/AMSR2 and Aqua/AMSR-E.
The AMSR Viewer provides daily images of observation data (brightness temperature) and estimated geophysical data since June 2002.

GCOM Sixth Research Announcement
JAXA is announcing the sixth research announcement (RA), which is the opportunity to conduct algorithm development, validation preparation, and application research for the first satellite of the GCOM-C (Climate) series, GCOM-C, as well as multi-sensor research mainly using data from GCOM-C.
The deadline for submitting proposals is November 1, 2015.

AMSR-E Slow Rotation Data

2013.12.2
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.
