IMERG Early/Late Run Precipitation Anomalies

Beginning on April 6, anomalies in the input SSMIS F17 precipitation estimates were detected in the IMERG Early and Late runs.  These anomalies manifest as episodic “swath shaped” areas of high precipitation over land which appear to affect most orbits to some degree.  The root cause is degradation in the 37 GHz V polarization channel.  On April 13 the issue was somewhat mitigated but we continue to monitor the situation.  Please let us know if you detect these (or other anomalies) in the IMERG Early and Late Runs after April 13.

Potential Upcoming Data Outages Due to Severe Winter Storm

The Washington, DC area is about to get hit with a record-level snow storm, with attendant disruptions to work schedules, travel, communications, and power.  If you find that the TMPA-RT products drop out, it is safe to assume that some combination of these effects is preventing production, and we will work to restore service when that is possible.
 

Hurricane Patricia Makes Landfall in Mexico

NASA Aids Response to Carolina Flooding

NASA Aids Response to Carolina Flooding

It was rain that wouldn't quit. A weather system fueled by warm moisture streaming in from the Atlantic Ocean on Oct. 3 and 4 relentlessly dumped between one and two feet of rain across most of South Carolina. The result was rivers topping their banks and dams bursting. Catastrophic flooding followed across most of the state, which has left residents in some areas without power or clean drinking water.
