TRMM Online Visualization and Analysis System (TOVAS)
| TOVAS News (2009/06/12) |
From TSDIS/PPS Help Desk:
As most of you are probably aware, TRMM experienced a PR instrument
anomaly on May 29, 2009 which affected all TRMM PR data resulting in
missing data since orbit# 65716.
If you have obtained any of the following TRMM PR products and associated
products (browse, CSI, etc) since that time, either through your
Standing Orders, Special Requests or through other means, please delete
the following products if you have not already.
1A21, 1B21, 1C21, 2A21, 2A23, 2A25, 2B31, 3B31, 3A25, 3A26
We anticipate that due to various outside factors (vacations, other
obligations, etc.) that some of our science users may not have had the
opportunity to look at this PR data obtained through Standing Orders, etc.
NASA and JAXA are currently working on a plan to switch to backup systems
on the spacecraft that will address the failure of a frequency
converter, system control and data processing unit associated with the PR
problem.
We will update you on this situation as new information becomes available
and sincerely appreciate your continued patience during this
period.

From TSDIS/PPS Help Desk:
PPS has discovered a processing error in TRMM 3B42 products from June 2008
through April 2009.
More specifically, for TRMM PPS 3B42 data starting in June 2008, the first
granule of the day, hour 0, is missing the IR merg data from hour 23 on
the day before. The other granules for the day are valid.
To resolve this error, PPS will be rolling back existing 3B42 and 3B43
products for these dates and start reprocessing beginning mid week. This
reprocessing effort will take several days to complete.
PPS will then be distributing corrected versions of the 3B42 and 3B43 TRMM
products for June 2008 through April 2009.
We sincerely apologize for this inconvenience and appreciate your patience
during this period.

Welcome to TOVAS, a member of the Giovanni (GES-DISC DAAC On-line Visualization and Analysis System) family, which provides users with an easy-to-use, Web-based interface for the visualization and analysis of Earth Science data.
Note: The Java Version uses Java applet for interactively selecting an area of interest. If you have difficulties in using the Java Version, please try the Non Java Version.
Continued improvement of this online tool, and the production and
dissemination of these data sets, depends on your (our users) informing us on
how you have used this tool and these data. We are particularly interested
in the value of this tool and these data sets to your research. Please send
your comments to help-disc@listserv.gsfc.nasa.gov.
