D -- SOFTWARE SUPPORT SERVICES FOR THE TIROS-N OPERATIONAL VERTICAL SOUNDER/REVISED TIROS-N OPERATIONAL VERTICAL SOUNDER (TOVS/RTOVS) SOL Contract 50-DDNE-4-00155 POC Aileen B. Redding, Contract Specialist, (301) 713-0839/Ina R. Merson, Contracting Officer, (301) 713-0839. DOC/NOAA proposes to negotiate, on a non-competitive basis, with Hughes STX under the contract 50-DDNE-4-00155 to increase the level of effort by approximately 15,000 man-hours over two years. The added hours are required for the acquisition of additional science software support services for the TIROS-N Operational Vertical Sounder (TOVS)/Revised TOVS (RTOVS) system. The additional science software support services includes the development of reactive science software for instrument malfunctions and both pre- and post-satellite launch operational preparations. Also included shall be upgrades to the LAN based EDGEIS data visualization software which has been developed by Hughes STX over the last eight years. This customized software runs on PCs and RISC workstations attached to the NESDIS/SIB LAN and is for the capture, transfer and display of satellite raw data and products. RTOVS science software algorithms must be evaluated and corrected or replaced to achieve current operational product accuracy. These algorithms include the following tasks: 1) day ''0'' capability for the creation of MSU''1B'' datasets; 2) re)hosting the Climate parameter Sub-System from TOVS to RTOVS; 3) instrument collocation of the HIRS/2I,MSU, SSU, and AVHRR; 4) instrument channel observations limb corrected to nadir; 5) cloud detection and cloud clearing; 6) upgrades to both the retrieval ''first guess'' and the temperature/water vapor retrieval; 7) corrections to the Radiosonde Retrieval Matchup Sub-System; and 8) re-hosting the TOVS automated Quality Control (data mislocation protection, stability departure parameters and trending statistics) into RTOVS. These product processing systems are extremely large and complex and run 24 hours per day as a two spacecraft operation. These systems include code written in VS FORTRAN, IBM Assembly Language, JCL, DOS, CLIST, MS Quick Basic and C-Language. The RTOVS software system is scheduled to replace the current TOVS when it can be made to produce products which are as accurate. The RTOVS system processes data from the same suite of instruments as TOVS except that RTOVS will include the AVHRR for cloud detection and cloud clearing. Vendors who believe they can provide the required services are invited to submit, in writing, an affirmative response demonstrating an ability to immediately assume the above duties without disruption to the current TOVS/RTOVS operations, and demonstrating a cost benefit to the Government. Any written responses must be received no later than 45 days after the publication of this synopsis. In order to be responsive, the correspondence must be accompanied by a written narrative statement of capability, including detailed technical information and other technical literature, sufficient to permit agency analysis in order to determine a bona fide capability to meet the Government's requirements. Responses without the required documentation will be considered non-responsive. This is not a formal notice of solicitation. See Note 22.(0177)
