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.

The mail server trouble has been fixed.
We can now receive the inquiry e-mails as usual.
Sincerely apologize for the inconvenience.

Due to the mail server trouble, some inquiry e-mails to xx@ml.jaxa.jp may not be reached to us.
Currently we are working on recovery efforts.Sorry for any inconvenience.

Realtime processing and provision resumed at 9:00 (UT) on March 19, 2019.
We will provide until the end of March the poducts that are currently not available.
We are sorry for the inconvenience.

[Mar. 19 2019 Published]
There has been a delay in the provision of AMSR2 products from 12:00 (UT) on March 18, 2019.
We are still working for recovery of service, and we will contact you when the service resumes.

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 (Then 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.

The AMSR2 global observation was temporarily suspended from 06:13 to 16:55 Dec. 16, 2018 (UTC) and observation data of that period was missed.
Currently, observation and data distribution of AMSR2 are back to normal.
We are sorry for any inconvenience caused.

GCOM-W1 Data Providing Service is going to be closed on June 29, 2018 (UTC). Thank you very much for your continued use of our service. AMSR series (AMSR2, AMSR-E, AMSR) products are also available on G-Portal (https://gportal.jaxa.jp/), but please use only G-Portal after June 29, 2018 (UTC). You need to register as a user to download products from G-Portal. If you have not registered yet on G-Portal, Please register your account.

The AMSR2 standard products have been suspended from January 1, 2017 (UT). Please wait for a while until the data distribution resumes. We are sorry for any inconvenience caused.

The Japan Aerospace Exploration Agency (JAXA) is announcing the first research announcement (RA) for each earth observation satellite project.
The deadline for submitting proposals is November 15, 2016.
-> How to apply

This version update will not influence on the accuracy of products because the retrieval algorithm itself is not changed. Regarding the old version products, JAXA is going to reprocess and provide them in sequence.
-> For more information, please refer to this page (User registration is required to use the products).

AMSR2 research products are being distributed on the GCOM-W Research Product Distribution Service website.

The AMSR2 observation was suspended from around 12UTC April 15 to 08UTC April 16, 2016. Now, AMSR2 observation was in normal status.

We are sorry for any inconvenience caused.

The AMSR2 global observation data distribution has been suspended from December 4, 2015 (UT), but the Japan and vicinity observation data (near-real time) distribution is continuing. Please wait for a while until the data distribution resumes. We are sorry for any inconvenience caused.

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.

After the AMSR-E observations were stopped, WindSat data had been used as alternative data. however, WindSat data were replaced by AMSR2 data since July 2012.

Precipitation images by Dual-frequency Precipitation Radar (DPR) onboard the GPM Core Observatory are added to the JAXA Tropical Cyclone Real-Time Monitoring web page.

AMSR-E Slow Rotation Data has been updated as follow.
<Data update period> From March 1, 2013 to February 28, 2014 (UT)
-> AMSR-E Slow Rotation Data

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
