Beginning on Monday February 04, 2019, the Level 2 and Level 3 GPM GPROF products will be produced with an updated monthly emissivity class file (see developers comments below). PPS will increment the product version for all Level 2 and Level 3 GPROF products starting with the first full orbit on data date February 1, 2019. The current version of these products will cease with data date Jan 31, 2019 and will remain unchanged. The new production version numbers/ designations will be incremented as shown in the table below. Data Source Product Version F16_SSMIS V05B F17_SSMIS V05B F18_SSMIS V05B...

This letter change means that data products were changed but no backward processing is undertaken. Only the products forward of the date/time have been altered. So, for GMI GPROF the vesion changed from V05A to V05B. Other instrument GPROF retrievals had a similar change but appropriate to their starting data product version. The algorithm itself did not change but some of the database profiles did. The algorithm team provided the following...
