99 -- ADVANCED GEOSTATIONARY SATELLITE (AGS) RETRIEVAL SOL 1-111-GLD.1973 DUE 072498 POC Lauretta E. Cole, Purchasing Agent, Phone (757)-864-2443, Fax (757) 864-9775, Email L.E.COLE@larc.nasa.gov WEB: Click here for the latest information about this notice, http://nais.nasa.gov/EPS/LaRC/date.html#1-111-GLD.1973. E-MAIL: Lauretta E. Cole, L.E.COLE@larc.nasa.gov. NASA/LaRC plans to issue a Request for Quote (RFQ) for AGS RETRIEVAL: 1. Given a LaRC design, radiometric model and operation scenario in July 1998, simulate the signal and compare spectrum accuracy with and without additional noise. Final report due 8/28/98. (Use currently available code that has been validated by experiment. 1 EA 2. Perform eigenvector regression analysis for the LaRC AGS FTS imaging sounder design to demonstrate system performance. perform second analysis to quantify affects to system performance by LaRC design changes; compare LaRC FTS sounding profile retrieval performance against the current GOES. 1 EA 3. Perform non-linear statistical/physical retrieval analysis for the LaRC AGS imaging FTS sounder instrument design to demonstrate retrieval accuracies for temperature, water vapor, and chemical trace gases profiles. Examine accuracy of sounding profiles as a function of varying instrument design parameters and their corresponding noise config- urations. Compare the LaRC instrument performance to current GOES system. Identify anticipated improvements to sounding accuracy due to the LaRC instrument design. 1 EA 4. Analyze incremental retrieval performance benefits associated with instrument configurations exceeding or below the baseline LaRC system in order to quantify the measurement capabilities and to provide advice in instrument design trade-off decisions. Final report shall document the optimal system configuration for various modes of operation. NOTE: for items 2, 3, and 4: Monthly progress reports to be delivered via e-mail by end of the third week of each month to LaRC AGS program manager (v.s.parsons@larc.nasa.gov) and instrument manager (j.a.woods-vedeler@larc.nasa.gov); progress reports and presentations to be delivered in August 1998 and December 198; final reports due May 1999, including documentation of trade studies performed, results obtained, summary of significant results and their applica-tion to the AGS imaging FTS sounder study; three referencable publications prior to May 1999.
