warn_icon.gif IMPORTANT MESSAGE Sep 25, 2016    2016 Final IMERG and TMPA replaced   

The 2016 Final IMERG (GPM_3IMERGHH.03 and GPM_3IMERGM.03) and Research Quality TMPA (TRMM_3B42.7 and TRMM_3B43.7) products have been retracted by the Precipitation Processing System and are now replaced. 

For 2016, the rain gauge data were erroneously not included, resulting in land estimates purely multi-satellite.  Note that this error does not affect estimates over ocean. Retro-processing to replace these data will commence on September 26, 2016.

The respective GES DISC derived Daily products (GPM_3IMERGDF.03 and TRMM_3B42_Daily.7)  are also replaced. 

Supporting the Hydrological Sciences Laboratory (HSL)

The Hydrology DISC supports data products generated by GSFC's Hydrological Sciences Laboratory (HSL). Data products from North America Land Data Assimilation System (NLDAS),  Global Land Data Assimilation System (GLDAS), and Famine Early Warning Systems Network (FEWS NET) Land Data Assimilation System
(FLDAS) can  be accessed through http, the Mirador search and access tool or the GrADS Data Server (GDS). The LDAS systems integrate data from multiple space-based Earth observing systems using advanced land surface modeling and assimilation techniques. These products support weather and climate forecast experiments, water resources applications, and water and energy cycle research.

The data are provisional and subject to change as model improvements are implemented and new input data sets become available.

Other atmospheric moisture and precipitation products are available from the AIRS and Precipitation Data and Information Services Centers.
