E-MAIL: Crystal E. Davis, Crystal. E.Davis1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Proposal, on a sole source basis in accordance with 10 U.S.C. 2304(c)(1) -- One responsible source, and 10 U.S.C. 2304(d)(1)(B) -- Unacceptable Delays. NASA/GSFC plans to obtain support from Space Applications Corporation of Vienna, VA, for a twelve-month extension (September 27, 1998 through September 30, 1999) to existing contract NAS5-32560. The contractor shall furnish the necessary personnel to provide scientific and technical support for the Climate and Radiation Branch and the Tropical Rainfall Measuring Mission Office (TRMM), in conducting a research program in modeling, simulations, and analysis of the Earth's climate and radiation involving aerosols, clouds, precipitation, atmospheric and surface parameters. The work involves processing and analyzing surface, aircraft, and satellite data, the development of remote sensing algorithms for deriving cloud, aerosol, and rainfall parameters, the development of numerical models for clouds and atmospheric circulation and hydrological cycle, as well as the analysis of interactions among clouds/aerosols, radiation, precipitation, and climate. SAC has gained specialized experience critical to the successful completion of the above missions. SAC has processed and analyzed data, developed and implemented satellite algorithms, and compiled and implemented computer software for cloud, rainfall, and climate models. Many of the cloud, rainfall, radiation, and climate models are specifically developed in the Climate and Radiation Branch and the Tropical Rainfall Measuring Mission Office and supported by SAC. The Climate and Radiation Branch, and TRMM are committed to specific and specialized missions regarding the delivery of scientific data, software, analysis tool, and physical and numerical models during the period from September 27, 1998 to September 30, 1999. The EOS AM-1 satellite is scheduled for launch in the spring of 1999. Technical expertise of SAC is unique to the missions of Climate and Radiation Branch andthe Tropical Rainfall Measuring Mission Office. Replacement of the incumbent by a new contractor will require intensive training of new contract personnel, which is time-consuming and expensive and would cause serious delays in meeting the mission requirement. Award to any other source for this twelve month period would cause unacceptable delays to the missions of the Climate and Radiation Branch and the Tropical Rainfall Measuring Mission Office. The phase-in time and lead time for new contractor personnel to become minimally experienced and functional to meet the Government requirement will certainly result in unacceptable delays in milestone schedules. This twelve month extension period is required to ensure continuation of support until the follow-on competitive procurement is awarded. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. See Note 22. An Ombudsman has been appointed. See Internet Note "B".
