Recommendation: The WG-MPAR Planning Process for the MPAR R&D program should implement frequent updating and improvement of the MPAR program plan to ensure planning robustness and relevance in the face of changing external conditions. As part of this process, the Program Plan should be periodically evaluated against program goals and objectives to ensure that they are both fully satisfied and remain relevant, as well as against the accomplishments of the R&D work. This evaluation should include annual external reviews, as suggested by Recommendation 3.5-6 of the JAG/PARP report.


The OFCM is the primary executive for the MPAR program as now constituted. Prime stakeholders are the Federal Aviation Administration (FAA), National Oceanographic and Atmospheric Administration (NOAA) (including the National Severe Storms Laboratory [NSSL] and the National Weather Service [NWS]), the Department of Homeland Security (DHS), and the Department of Defense (DOD) (including the US Air Force, US Navy and US Army). Secondary MPAR stakeholders include the Federal Emergency Management Agency and the US Coast Guard, the Federal Highway Administration (FHWA), National Aeronautics and Space Administration (NASA), the Departments of Agriculture, Energy and Interior, and the Office of the Director of National Intelligence, as well as the NextGen Joint Planning and Development Office (NextGen JPDO).

Primary stakeholders that have a stated commitment to fund MPAR research and development activity are:

  • FAA—for a cost-effective backup to the next-generation cooperative surveillance system and a possible replacement for legacy radars; FAA is currently funding phased array radar R&D.

  • NOAA—for continued funding of the National Weather Radar Testbed and additional funding for a MPAR risk reduction program beginning in FY 2010.

As yet, neither DOD nor DHS have promised to fund MPAR activities, although discussions are underway.

Both the OCFM and FAA agree that the large cost of R&D for MPAR and the need for interagency harmonization of requirements will require extensive interagency collaboration and the eventual creation of an MPAR Joint Inter-Agency Program Office.


As noted in the JAG/PARP report, planning for MPAR is driven by many factors including the rising Operations and Maintenance (O&M) costs of legacy radar platforms and societal expectations for improved performance in weather surveillance. It is also affected by the emergence of the NextGen and its reliance upon cooperative transponder
