E-MAIL: Lynette Harrington, Mildred.L.Harrington.1@gsfc.nasa.gov. NASA/GSFC plans to issue a Request for Proposal (RFP) for a sole source follow-on contract with the University of Colorado at Boulder for operation and maintenance of a Snow and Ice Distributed Active Archive Center (SI DAAC) as one element of NASA's Earth Observing System Data and Information System (EOSDIS). The EOSDIS is a comprehensive data system which manages the data from Earth science research satellites and field measurement programs of NASA Mission to Planet Earth (MTPE). The SI DAAC is currently operated as part of the National Snow and Ice Data Center (NSIDC). The SI DAAC serves the polar oceans, ice, and snow research communities with data and data products primarily generated from Earth observation satellites. It processes, archives, and distributes sea-ice and snow-cover parameters from passive-microwave sensors and related in situ data. Tasks assigned include those assigned to all EOSDIS DAACs: user services, product generation, data and information management, archival and distribution, and related science support. The statutory authority permitting other than full and open competition is 10 U.S. Code 2304(c)(3) -- Industrial mobilization; engineering, developmental, or research capability; or expert services. See Numbered Note 26. RFP will be released on or about July 31, 1997. Firm date for receipt of proposals will be stated in the RFP. All responsible sources may submit a proposal which shall be considered by the agency. See Number Note 22.
