    3. 3 System Requirements System Parameters Network Connectivity SAN connectivity Remote Access

    4. 4 System Parameters Operating Systems AIX 5.3 CPU 45 minutes per orbit (estimated) RAM 8 Gigabytes (estimated) Disk Storage and Directories Web Server: 10 Gigabytes (250K Skew-T gifs) Diamond: 10 GB (images) + 35 GB (MD files) = 45 Gigabytes

    5. 5 Network Connectivity Development Transfer GIFs from North ? gp50 Set up Firewall rules SFTP images Operational Transfer GIFs from Diamond ? gp5 Set up Firewall rules SFTP images

    8. 8 SAN Connectivity Continued System Services SSH SFTP Mail forwarding SSI (server side included)

    9. 9 Remote Access Groups that will have access to this system OSDPD STAR

    10. 10 Application Requirements User Requirements Data Source

    11. 11 User Requirements Currently operationally producing SKEW-Ts from GOES Soundings SAB has requested the same capability for POES Soundings

    12. 12 Data Sources Input Data Rotating Orbital Data File (RODF) Composite Area Files (AVHRR) Output Data Retrieval McIDAS Data File (MD) or Meteorological Data File? GIFs Skew-T MD Gradient wind MD Skew-T GIFs

    14. 14 Basic Design

    15. 15 RODF-MD File Processor

    16. 16 Processing Sequences Processing Sequences Grid Spacing 0.5 Composite Polar Image

    17. 17 Global RAOB Stations Here is a map of global radiosonde stations colored by radiosonde types. Globally there are 13 radiosonde types and about 900 stations www.cosmic.ucar.edu/.../presentations/wang.ppt Here is a map of global radiosonde stations colored by radiosonde types.

    18. 18 Web Page

    19. 19 System Architecture Hardware p570 Scheduler Same as ATOVS Runs after RODF is created Monitoring Log files Issue an email to developer if an error occurs Programming Languages Fortran 77 C McIDAS Coding Standards OSDPD Standards Revision Control RCS

    20. 20 Document Requirements

    21. 21 Documentation Executable code Perl and Bash Shell Scripts System Description Interface Control Users Manual Systems Maintenance Manual Operations Manual

    22. 22 Testing of the Code

    23. 23 Unit Testing C1 Confirm that necessary parameters for computing the gradient winds are in the PRET MD and within the expected value range C2 Confirm that all stability parameters in the POES MD file are present and are within the expected value range C3 Confirm that gradient winds are computed and within the expected value range C4 Confirm that the SKEW-T MD file has all the stability and gradient wind information within the expected value ranges C5 Compare values in the POES SKEW-T GIFs against values in the MD file Additionally, compare against collocated GOES SKEW-T GIFs

    24. 24 System Testing Confirm submission of SKEW-T job from ATOVS orbital processing Confirm that composite imagery is being generated with desired frequency and is making it to Diamond

    25. 25 Web Testing Confirm that GIF images are being pushed to the web server Confirm that web pages are getting updated with proper frequency

    26. 26 Milestones and expected start date for operation

    27. 27 Milestones and expected start date for Operation
