Replacement GPM Ka/Ku L1B products (2017-03-19) for orbit 17356

PPS received replacement GPM Ka/Ku L1B products from JAXA and will reprocess the affected data. If you have already obtained products with orbit #17356 from our archive or through a standing order, etc., please discard and use the replacement products. PPS has replaced the following GPM Ka/Ku L1B data: GPMCOR_KUR_1703190533_0705_017356_1BS_DUB_04A.h5 GPMCOR_KAR_1703190533_0705_017356_1BS_DAB_04A.h5 ------------------------------------- PPS will reprocess these affected downstream products shortly. 2A.GPM.Ka.V6-20160118.20170319-S053318-E070552.017356.V04A.HDF5 2A.GPM.Ku.V6-20160118.20170319

Upcoming IMERG version update to V04A

The algorithm for the Integrated Multi-satellitE Retrievals for GPM (IMERG) Early and Late Runs has now been upgraded to Version 04. The transition to V04 is planned to happen on Monday, March 13 by 15 UTC at PPS and the new data should start flowing down to the GES DISC as well. Access and data fields continue to be the same as for Version 03, except the version number is 04A. Initially, the data records begin on 5 February 2017 for the Late Run, and about 5 hours before the time when PPS begins processing after the switchover for the Early Run. Version 04 supersedes all prior IMERG versions

GPM Combined Radar-Radiometer Precipitation Algorithm Theoretical Basis Document (ATBD)

Date Last Updated
July 1st, 2022
Document Description

The GPM Combined Radar-Radiometer Algorithm performs two basic functions: first, it provides, in principle, the most accurate, high resolution estimates of surface rainfall rate and precipitation vertical distributions that can be achieved from a spaceborne platform, and it is therefore valuable for applications where information regarding instantaneous storm structure are vital.

Goddard Convective-Stratiform Heating (CSH) Algorithm

Document Description

Latent heating (LH) cannot be measured directly with current techniques, including current remote sensing or in situ instruments, which explains why nearly all satellite retrieval schemes depend heavily on some type of cloud-resolving model or CRM (Tao et al. 2006, 2016). This is true for the current CSH algorithm (Tao et al. 2010).

Jan. 2016 GPM IMERG and Jan.-Jun. 2016 TMPA 3B42/3B43 Data Products are Being Recalled and Replaced

UPDATE 9/27/16: January 2016 IMERG has been regenerated and posted. This was necessary due to an error that omitted the gauge analysis in the Final products. Also, 3B42/3B43 have been recomputed and posted. Let me know if you have any further questions. --- PPS has removed the January 2016 GPM IMERG and January through June 2016 3B42/3B43 TMPA products from our ftp archive: ftp://arthurhou.pps.eosdis.nasa.gov/ and STORM: https://storm.pps.eosdis.nasa.gov/storm/ The GPM science team discovered that the IMERG final products for Jan 2016 and the Jan-Jun 2016 TMPA 3B42/3B43 products for which we
