E-MAIL: Veronica C. Stubbs, Veronica.C.Stubbs.1@gsfc.nasa.gov. NASA/GSFC plans to negotiate a one-year extension to Contract NAS5-32371 with Atmospheric Environmental Research, Inc., (AER), beyond the current end date of the contract (2/28/98)). This extension is required to complete scientific investigations relevant to the atmospheric effects of stratospheric aviation. NASA is charged, through the Office of Aeronautics Atmospheric Effect of Aviation Program (AEAP) with providing an assessment report on the possible environmental effects of engine exhaust from a hypothetical fleet os stratospheric aircraft on the stratospheric ozone layer by the end of 1998. AER is the only known source to have developed the necessary interactive models and scientific expertise to address all program objectives. AER has participated in model development and intercomparison activities since 1970. The AEAP is scheduled to end in 1998 and all assessment reports on possible environmental effects must be submitted by the end of the program. Statutory authority for this sole source procurement is 10 U.S.C. 2304(c)(1) -- Only One Responsible Source.
