A -- DEVELOPMENT OF NIST STANDARD REFERENCE DATA PRODUCT SOL 53SBNB867059 DUE 041698 POC Julie Liu (301) 975-6727, FAX (301) 975-5007 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) has a requirement for services to develop a NIST Standard Reference Data (SRD) Product that contains spectral ultraviolet radiation data acquired since March 1997 at four exposure sites (in Phoenix, AZ; Miami, FL; Edgewater, MD; and Gaithersburg, MD) using the Smithsonian Environmental Research Center's (SERC) 18 channel filter wheel radiometer, which contains 18 interference filters with nominal center wavelengths from 290 to 324 nm at 2 nm intervals. Every minute, the radiometer transmits three lines of data to a data acquisition system. The first line consists of the instrument identification and the current data and time. (The time is at the minute after the data was recorded.) The second line contains 20 channels of average voltages. Of the 20 channels, 18 are for spectral irradiance data from 290 to 324 nm, and the other two are dark signals. The third line consists of diagnostic data for the device. The spectral irradiance data is internally stored in the radiometer and is periodically downloaded to a computer at NIST and SERC where the minute data for each center wavelength is averaged over contiguous 12-minute periods and is corrected for any optical changes in the radiometer. This 12-minute data has been collected for each of the four exposure sites since March 1997, and it is the management, storage, and retrieval of this collected data which is the prime objective of this procurement. In addition to the management of data, effort shall be made to enhance the computer network connecting each of the four radiometer sites. This enhancement shall involve near real-time display of the radiometric output from each radiometer at all four exposure sites. TASKS TO BE PERFORMED: (1) develop and publish SRD Product; (2) upgrade Solar Data Network (SDN); (3) expand SDN for global presence; (4) establish an Internet presence for coating service life prediction community; and (5) develop common data formats for service life prediction data. The periodof performance shall be from date of contract award through eight months thereafter. All responsible sources may submit a quote which shall be considered by the Agency. Requests for quotation packages should either be mailed to the National Institute of Standards and Technology, Acquisition and Assistance Division, Building 301, Room B117, Gaithersburg, MD 20899-0001, or faxed to: (301) 975-5007.
