A globally diversified data acquisition and distribution network will serve as a resource for all interested stakeholders (such as those involved with agriculture, public health, water resources management, aviation safety, etc). The goal is a seamless transition of precipitation products from TRMM to GPM to maintain continuity in data records. All routine precipitation products processed along the GPM orbit will be archived and distributed by the Goddard Earth Sciences Distributed Active Archive Center (GDAAC).

The data information and archiving system for GPM is known as the GPM Precipitation Processing System (PPS). It builds on the existing mission-specific TRMM Science Data and Information System (TSDIS), but is now a generic framework that can be easily adapted for use by any precipitation mission. The PPS will reside at the NASA/Goddard Space Flight Center. Additional data processing systems are envisioned at JAXA Earth Observation Research and Application Center (EORC) and the European Space Agency (ESA) European Space Research Institute (ESRIN) in Tokyo, Japan and Frascatti, Italy respectively. Each of these centers will make important contributions to the overall GPM mission.
