Reprocessing several files of All-weather Sea surface Wind speed

We reprocessed several Level 2 and 3 files of the AMSR2 All-weather Sea surface Wind speed (ASW) research products(V301) due to problem in missing data handling.
All affected files (Ten L2 files from July 2012 to December 2018 and L3 files that use those affected L2 files as input) have been replaced with new files. Details are as listed.
We are sorry for any inconvenience caused.

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.
