As a more formal way to become partners on GPM, it is recommended that NOAA and NASA establish a new component to the existing Joint Center for Satellite Data Assimilation that will focus on precipitation measurements and applications. Ultimately, this center will encompass much of NOAA’s precipitation-related activities. Through this center, NOAA will contribute resources to support NOAA Science Team members, a joint Research Announcement, joint field campaigns, and data processing/archival. To accomplish this, NOAA should incorporate the potential benefits of GPM within its ongoing Program Baseline Assessment (PBA) and Gap analysis. For example, a gap was recently identified within the Hydrology Program regarding the insufficient number of global precipitation observations. Clearly, GPM would help NOAA alleviate this gap. Through the PBA process, long-term funding for activities related to GPM can be secured. However, in the short term, NOAA should provide seed funds beginning in FY 04 to formalize its partnering commitment to NASA. Once this has been established, joint, national-based partnering meetings between NASA and NOAA should be held on a regular basis.
