Data News


The PPS (Precipitation Processing System) will be down Sunday September 18, 2016 -estimated time from 10:00am to 6:00pm EDT (14:00 - 22:00 UTC) for Special Unscheduled Maintenance.

Please note: although it is unlikely, due to unforeseen events PPS systems might be down overnight and only be available starting Monday morning, September 19, 2016.

During this time, all data transfers between PPS source and its consumer systems (GDAAC/DISC) as well as Science User services (FTP and STORM access) will be unavailable.

You may e-mail “sysgods@mail.pps.eosdis.nasa.gov” if there are any urgent matters requiring our immediate attention during this period.

FNMOC is behind in providing the SSMIS data used in IMERG. Therefore, the Early and possibly Late IMERG products will contain less satellite estimates and be of somewhat lesser quality.  

FNMOC stopped providing data around 00 UTC today (8 September 2016), meaning there has been no  data available from the three operational SSMIS sensors to the TMPA-RT datasets.  As a result, more lower-quality IR-based estimates are being used.  In addition, if there are dropouts in the IR data, there is a higher probability that gaps will appear in the combined product, 3B42RT.  We will update the situation when it changes.

The PPS (Precipitation Processing System) will be down today, July 19, 2016 from 8:00am -14:00pm EDT (12:00 - 18:00 UTC). for scheduled maintenance.

During this time all data transfers between PPS source and its consumer systems (GDAAC/DISC) as well as Science User services (FTP and STORM access) will be unavailable.

You may contact PPS Operations at helpdesk@mail.pps.eosdis.nasa.gov

You will be informed when PPS systems become available. We apologize for any inconvenience this may cause.

We are contacting you to report an problem where Version 4 GPM data products could not be read using the 4.2.2.1 version of netCDF.  Users are recommended to upgrade to netCDF 4.3.3.1 or later.

Any software (OPeNDAP, etc.) that uses older than netCDF Version 4.3.3.1 (what we tested, versions earlier in the 4.3 series may also work) will not be able to read GPM DF5 Version 4 data.

With the GPM Version 04 Update, PPS is also rolling out an interactive GPM NRT Viewer. This tool displays NRT Level 1C GMI, Level 2A GPROF, and Level 2A DPR data as soon as it is available in the NRT archive on a three-dimensional globe. 

Fields such as brightness temperature and surface precipitation rate are available for visualization, comparison, and improved data acquisition decision-making.  You may Leave it running continuously as data refreshes with each segment, or use the navigation dropdown to look at specific events and time periods from the previous twelve hours. 

This viewer is useful for users that don't wish to download the data but look at NRT data as it arrives. Perhaps as a result of seeing something interesting they may also wish to ftp the data.  The viewer gives another approach for using GPM NRT data.

Explore GPM NRT data as not possible previously. The viewer is available at:

https://storm.pps.eosdis.nasa.gov/storm/cesium/GPMNRTView.html

Please make sure that you have the latest version of a browser that support the https protocol well.

Your username and password for STORM is the same that you use to access NRT data.

Due to continuing, intermittent anomalies in the F17 SSMIS 37v channel, starting from April 13, 2016 (Orbit # 48713 : 18:29:36) and forward all 1C F17 products will flag the 37V channel as bad data and the Brightness Temperatures will be missing.

We apologize for any inconvenience or problems that this may cause and appreciate your understanding and patience.
Please let us know if you have any questions or concerns. 

UPDATE 5/10/16 1:06pm EDT: Access to PPS systems and services have been restored.   Thank you for your patience during this period. Please report any problems;  and do not hesitate to contact us if you have any questions or concerns.

The Precipitation Processing System (PPS) is currently experiencing a hardware problem which is impacting PPS data production,  ftp archive access (arthurhou, trmmopen, etc.),  and PPS web sites (STORM, THOR, etc.) today - Tuesday May 10,2016.

Our system programmers are currently working on this problem and hope to restore services as soon as possible.  We will keep you informed as the situation changes.

We apologize for any inconvenience that this may have caused and appreciate your understanding and patience.
