A -- LABORATORY STUDIES OF CHEMICAL AND PHOTOCHEMICAL PROCESSES RE LEVANT TO STRATOSPHERIC OZONE SOL RFP5-13749/210 POC R.L. Williams, Contract Specialist, 301-286-7859; Cynthia L. Tart, Contracting Officer, 301-286-3318. This is a notice of intent to issue Request for Proposal (RFP) 5-13749/210 on a sole-source basis to Aerodyne Research, Inc. (ARI). The proposed procurement will require the Contractor to perform research as part of the Upper Atmosphere Research Program. The research will include design and construction of a turbulent flow reactor for radical kinetic measurements, measure the rate of H02 + ozone reaction in a turbulent flow reactor at stratospheric temperatures and pressures, measure rate constant for the H02 and N02 association reaction at stratospheric temperatures and pressures, measure rate of N0 + ozone reaction in a turbulent flow reactor at stratospheric temeratures and pressures, and measure product branching ratios for OH + and H02N02 reaction in a low pressure flow reactor at stratospcheric temperatures. In addition to the above, ARI personnel will participate in the NASA Data Evaluation Panel, bearing primary responsibility for the heterogenous chemistry assessment. This effort involves innovative research, focusing on the details of stratospheric chemistry and our ability to predict future changes. ARI has focused its efforts in this and related areas within NASA sponsored programs during the past three years. A peer review determined that the ARI proposal demonstrated a unique and innovative concept which is not otherwise available to the Government, and which does not resemble the substance of a pending competitive acquisition. Therefore, ARI is uniquely qualified to perform this research. The statutory authority for Other Than Full and Open Competition is U.S.C. 2304(c)(1), Only One Responsible Source. Any other potential offeror desiring consideration should fully identify their capability to provide these services or submit a proposal within fifteen (15) days of publication of this synopsis to the Goddard Space Flight Center office and the individuals listed abvove.
