Description

The National Oceanic and Atmospheric Administration (NOAA), proposes to negotiate on a sole source basis under the authority of 41 U.S.C. 253(c)(1) with Yankee Environmental Systems, 101 Industrial Road, Turner Falls, MA 01376 for a pyranometer that measures global solar radiation reaching the surface of the Earth in the UV-B spectral range. Specifications are as follows: The instrument should be designed for long-term use in the field, with only minimal routine maintenance. The radiometer should measure UV-B global radiation in the range from 280 to 330 nm. Its spectral response function should peak between 280 and 310 nm and fall off sharply on either side of that band. The cosine response of the instrument should be better than plus or minus 5 per cent for solar zenith angles from 0 to 60 degrees. Because these instruments will be deployed in remote areas, year-round, the instrument should be thermally stabilized at equal to or greater than 40 degrees C in order to ensure that there will be no ice buildup on the body of the instrument in very cold weather. Finally the manufacturer should ensure long-term stability in the calibration. The spectral radiometer that is needed for the SURFRAD network should measure global and diffuse radiation in at least six sharply-defined spectral bands the cover the visible and near infrared portion of the solar spectrum. The response functions of these bands should be very narrow and centered near 415, 500, 615, 673, 873, and 940 nm. In addition, there should also be a broad-band channel to measure total solar global and diffuse radiation. The sampling rate should allow up to four samples per minute. The cosine response should be better than 5 per cent for solar zenith angles from 0 to 75 degrees. Because these instruments will be deployed year-round in various climates across the United States, they should be designed to operate in a temperature range from minus 20 to 50 degrees C. The manufacturer should provide and ensure the long-term stability of the calibrations for each spectral band. The sky imager must include a fully automated color camera and software package. Resolution of the camera should be at minimum 352 x 288 color at 24-bits. The system should be able to sample the hemispheric sky once per minute and operate in a temperature range from minus 30 to 34 degrees C. The system should be internet ready and equipped with 10Base-T ethernet protocol for real time access to hemispheric images. This synopsis is issued for information only. No competitive solicitation is planned. No award will be made on the basis of requests in response to this notice. Information submitted in response to this notice will be used solely to determine whether or not use of competitive procedures to fulfill this requirement would be in the Government=92s best interest and must address qualifications pertinent to this requirement. This announcement is being issued under the Simplified Acquisition Procedures, FAR Part 13. Estimated government cost is between $25,000 and $100,000.
