A Global Tour of Precipitation from NASA

A Global Tour of Precipitation from NASA

A Global Tour of Precipitation from NASA shows how rain and snowfall moves around the world from the vantage of space using measurements from the Global Precipitation Measurement Core Observatory, or GPM. This is a joint mission between NASA and the Japanese Aerospace Exploration Agency (JAXA) and offers the most detailed and worldwide view of...

Developing Tropical Storm Triggers Deadly Landslides in Sri Lanka

Developing Tropical Storm Triggers Deadly Landslides in Sri Lanka
A storm does not have to be especially powerful in terms of its winds to be deadly. Such is the case with Tropical Cyclone 01B (TC 01B) in the Bay of Bengal. Despite only reaching minimal tropical storm intensity just this morning at 06 UTC 18 May 2016, the system has been responsible for dumping heavy rains in and around Sri Lanka and southern Indian over the past few days as it tried to organize itself in the southwestern Bay of Bengal. This set the stage for two massive landslides, which buried 3 villages in south central Sri Lanka. So far, although several hundred people have been rescued

New GPM NRT Swath Product Browser

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

F17 SSMIS L1C Data Product Update

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.

Recent IMERG Anomalies

Below are a few recent satellite anomalies of note that may have affected the quality of the IMERG precipitation products. 10 May 2016: The data flow from the Himawari-8 GEO satellite was interrupted for 57 hours, 7 May, 05 UTC – 9 May, 14 UTC and during that time there is a continuous zone of missing values in the IR precipitation data in the center of the Himawari-8 sector (over Japan), where data from the adjoining GEO satellites are unable to fill the gap. The IR-based displacement vectors were therefore computed using the standard fallback of spatial interpolation. 20 April 2016

PPS Experiencing Temporary Service Outage

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

GPM Measures Deadly Flooding Rainfall

GPM Measures Deadly Flooding Rainfall
Over the past week extreme rainfall caused flooding that resulted in the deaths of four in Haiti and the evacuation of over 2500 people in the Dominican Republic. The GPM core observatory satellite saw a line of heavy rainfall on the eastern side of the Dominican Republic when it flew over on May 8, 2016 at 0428 UTC. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data that were used to estimate rainfall. This precipitation is shown on a top-down satellite view. Powerful storms were measured dropping rain at a rate of almost 300 mm (11.8 inches)

F17 SSMIS Data Processing Resumes

PPS will be restarting F17 processing. There will be 88 1C products that will be retracted and reprocessed for the following dates: 2016-04-13 (18:29:37) to 2016-04-19 (23:56:53). Starting from this date 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 contact us if you have any questions or concerns.

Severe Weather In Tornado Alley And Eastward (May 2nd Update)

Severe Weather In Tornado Alley And Eastward (May 2nd Update)
Severe spring thunderstorms frequently spawned tornadoes from the Gulf Coast north and eastward during the past seven days. From April 25 to May 2, 2016 there were over 67 tornadoes in the United States reported to the National Oceanic and Atmospheric Administration (NOAA). Many of these tornadoes were located in an area that includes the states of Texas, Oklahoma, Kansas, and Nebraska. This area of the Great Plains has been labeled Tornado Alley due to the many tornadoes that occur there this time of year. Gulf moisture clashing with frontal systems moving over the United States provided much
