future improvements in model physics, retrieval, or observational capabilities. The Pilot Evaluation of High-Resolution Precipitation Products is an example of a “grassroots” effort in data impact evaluation. Presently, this effort relies on volunteers.

User Education and Training

User education, training, and feedback will be an important component in the success of the GPM mission. In the years leading up to the GPM launch, user conferences hosted by NOAA and NASA could help familiarize and educate potential users with the types of data and products that will become available. These conferences could continue through the post-launch and NOAA control phases, providing a vehicle for useful feedback from the community. NOAA has already set a precedent for such user conferences: the GOES-R program office has been holding such conferences for several years. These conferences aim to educate potential users about GOES-R and also to gain early feedback from the community on potential products, coverage, frequency, and resolution. In this regard, the user conferences are held with the goal of infusing user requirements into the design, operation, and implementation of GOES-R services.


NOAA’s partnership with NASA for the GPM mission is essential to ensure that NOAA’s operational forecast models, forecasters, and product users are ready for GPM data as soon as possible after launch of the GPM core satellite. Joint NOAA-NASA activities are already under way, and increased NOAA support for these activities is needed to effectively engage in GPM planning. In addition, NOAA can start preparing for GPM now within the agency to make best use of the time available before launch of the GPM core satellite. NOAA’s preparation activities are framed in Chapter 5 within the context of a three-phase strategic plan for GPM.
