66 -- AUTONOMOUS INFRARED RADIOMETER FOR THE CALIBRATION OF SATELLITE MEASUREMENTS OF SEA SURFACE TEMPERATURE SOL N00173-98-Q-6002 DUE 101598 POC Contract Specialist, Richard D. Sewell, Code 3235:RS; Contracting Officer, John W. Adams, III, Code 3230, (228) 688-5784 E-MAIL: Click here to contact the Contracting Officer, John, SSCCONTRACTS@nrlssc.navy.mil. The Naval Research Laboratory (NRL-SSC) intends to negotiate a contract on the basis of Other Than Full and Open Competition IAW 10 USC 2304(c)(1) with the Southampton Oceanography Center, England, for an autonomous infrared radiometer. The required radiometer will be used for the calibration of satellite measurement of sea surface temperatures. The required system (a) shall include a self-contained power supply; (b) shall include an internal calibration system using thermally-controlled calibration bodies which are referenced before and after each sea view; (c) shall include a built-in correction for reflection of either sun or near-surface atmosphere; (d) shall include a built-in electronics system and algorithm which employs all instrument components to deliver radiometric sea surface temperatures accurate to 0.1 C every few minutes for satellite uplink; (e) shall include at least 3 MB of on-board data storage capacity; (f) shall be designed, developed and produced to maintain functional, operational, structural and waterproof integrity in the presence of salt contamination (both dry and wet deposition), bird attacks, marine animal attacks, spray, rain, lightning, large waves, corrosion, human curiosity, and other conditions which may be present in the marine environment; (g) shall be capable of autonomous buoy-mounted operation for periods of at least three months;(h) shall require minimum maintenance after retrieval from deployment; (i) shall be modular in design; (j) shall be light weight (25 pounds maximum); (k) shall include capabilities which allow radio interrogation from nearby sites for ease in diagnosing prototype imperfections; and (l) shall possess a detector which is accurate in a radiometric range of +200 to -270 C. with a frequency range the same as current satellite sea surface temperature sensors such as GOES and AVHRR. No telephone requests will be accepted in response to this notification. All responsible sources are invited to identify their interest and capability to respond to this requirement. Only written information received directly from requestors will be considered. Posted 09/14/98 (W-SN249241). (0257)
