PPS will reprocess the entire TRMM era level 2 and level 3 GPROF products. Currently TMI level2 and level3 GPOF products are under evaluation. PPS will reprocess TMI GPROF products as soon as they are approved, and inform user community once they are available.
The other note is that the GANAL ancillary data is not available back through the TRMM era. Therefore, only the GPROF products using the ECMWF ancillary data will be produced.
As always, all processed TRMM era level2 and level 3 GPROF products will be held until they have been reviewed and verified by the Science Team. The processed TRMM era level 2 and level 3 GPROF products will be released to the public upon their approval.
