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
