MHS NOAA-19 Data Processing Stop (PPS Will Halt NOAA-19 1C and GPROF Data)

Post Date: 
09/19/2019

PPS will halt the NOAA-19 L1C and GPROF products for the time being due to problems with the input received.

Indications are that the NOAA-19 MHS channel 2 has failed.   The input data (MSPPS_ORB) used for producing the NOAA-19 MHS L1C product is flagging all the Ta as missing, and as a result the L1C and GPROF products for NOAA-19 have ceased.

We will inform you when and if we have any new details or announcements.

Thank you for your attention and patience during this time.
 

Dorian Stalls, Brings Heavy Rain to Bahamas

Hurricane Dorian Brings Heavy Rain to Bahamas

In addition to the powerful winds that have raked the northern Bahamas over the past few days, Hurricane Dorian’s slow motion has brought very heavy rainfall to the islands as well.  Dorian first formed into a tropical depression on the 24th of August about 800 miles east southeast of Barbados in the Lesser Antilles from an area of low pressure; the depression was quickly upgraded to a minimal tropical storm and named Dorian by the National Hurricane Center (NHC) later in the day.

UPDATE 9/9/19:

On Monday morning, September 9, Hurricane Dorian was a post-tropical storm after a mid-latitude weather front and cold seas had altered its tropical characteristics over the weekend. On Saturday and Sunday, Hurricane Dorian struck eastern Canada, causing wind damage and bringing heavy rainfall.  According to the Associated Press, a peak of 400,000 people were without power in Nova Scotia, Canada, because of Dorian.

IR Anomalies in Early and Late IMERG

Post Date: 
08/28/2019

Beginning with August 19, 2019 at 13:00 UTC, noise in the form of random horizontal lines over the Eastern Pacific began appearing, with most of the problems appearing each following day in the 12:00, 12:30, and 13:00 half-hours, with at least one instance of 13:30.  This was traced to noise in the GOES-W Tb’s (as the result of the faulty sensor cooling system), which made it past the filtering at CPC, where the Merged Global 4-km IR dataset is assembled.  The Early and Late datasets contain these errors, which will be dealt with in the Final computation.

TRMM era IMERG Completed & End of FTP at PPS

Post Date: 
08/16/2019

IMERG is now available back to June 2000 of the TRMM era.  Both the 'early'
and the 'late' products have been retrospectively processed.  These products are available in the same location on the jsimpson.pps.eosdis.nasa.gov FTP server as the current GPM IMERG products: /NRTPUB/imerg/early/YYYYMM and /NRTPUB/imerg/late/YYYYMM.

We are in the process of retrospectively processing the GIS-friendly versions and accumulations of these IMERG products. This is likely to be completed by the end of September 2019.
