PPS is releasing the DPR and downstream data for distribution from April 22, 2020 - April 30, 2020. There are continuing short data outages for the radar that are being investigated and corrective measures are scheduled to be applied on May 14, 2020. PPS will be releasing May 2020 data in stages with an expected return to normal data availability soon after the corrective measures are applied.

TRMM era IMERG Completed & End of FTP at PPS

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.

PPS is Reprocessing TRMM PR Data as TRMM GPM, Version 06A HDF5 products in Early July 2018
