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. |

| TOVAS New Release (2008/09/12) |
|
Giovanni TOVAS is in transition to a new web host. Two new transitioned instances of TOVAS have been released:
Several new functions and parameters have been added along with additional data download formats (HDF, NetCDF and KMZ).
As planned, all current TOVAS instances, listed below in this page, will be similarly converted to the new system. |
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.
