Presentation materials of the 5th GPM International Planning Workshop are available. Please see the workshop page.

"TRMM Typhoon Real-Time Monitoring" site was opened. You can see the images of typhoons around Japan captured by TRMM.

From Dec. 2 to 5, this site will be temporally unavailable due to legal inspection of electrical equipment. We apologize for your inconvenience.

The following pages will be unavailable at November 25, 10:00-17:00(JST) due to web server maintenance.

The hurricane KATRINA brought the southern U.S. serious damage. Images of KATRINA are here.

The 5th GPM International Planning Workshop will be held from 7 (Mon) to 9 (Wed) November 2005, at Shinagawa Prince Hotel, Tokyo, Japan. In the Workshop, we will update the GPM status, and discuss the plan for full utilization of the GPM data not only for science but also for operational applications. For more details, click here.

There have been some problems with recent PR data where some scan lines are missing. These problems are occurring in the transmission process between satellite and ground station. So, all PR data including level 1 and higher are affected by the problems.
The known affected dates and orbits are as follows:

      Date               Orbit
      July 14, 2005   43661
      July 16, 2005   43692, 43693
      July 18, 2005   43723, 43724
      July 19, 2005   43739, 43740
      July 20, 2005   43753, 43754, 43755

The problems have not been occurred since July 21. In addition, it was known that this type of interference also occurred in November 2004 and in May 2005.
NASA is investigating the cause and the possibility that it happens again. Except missing scan lines, all data were processed normally.

New Orbit Viewer (Version 1.3.5) released.
   - Still capable of viewing all V6 products.
   - Enhanced color tables for new V6 fields "e_surfRain".
   - First Mac OS X compatible version.
   - Continued SGI IRIX, Linux and Windows XP support.

--> New version available from the TSDIS web site.

We opened the JAXA/EORC Tropical Cyclone Database, in which both TRMM and Aqua/ADEOS-II pages were integrated. So you can search tropical cyclone data observed by TRMM/PR, TMI, VIRS, Aqua/AMSR-E and Midori-II at the same time. Furthermore, TRMM/PR three-dimensional movies newly appeared.

JAXA/EOC released new version of 3A25 product (V6A) processed by improved algorithm (V6.17) which corrected an error. The past processed 3A25 products are also being reprocessed.

PR Specific area data (Japan area, GAME area) acquired after 2001 was added to the data previously uploaded, the period of May - Sep., 1998 - 2000. Version 6 products, released last June, also started to be subset and upload to the server.

According to NASA, an error has been discovered in the 3A25 V6 algorithm that results in the corruption of the shallow rain fields below. These fields should NOT be used.

    shallowRainPix1

We apologize for any inconvenience this might cause.

This document describes the algorithm of the Precipitation Radar of TRMM. This is the final edition for Product Version 6. See the Documents page.

2004 edition of "Global Rainfall" and "Global Sea Surface Temperature" posters were uploaded to the Gallery page.

NASA announced that the operation of TRMM will be continued through spring 2005.
