| At line 2 added 51 lines. |
| + Summary |
| + |
| + Obtain target minus comparison SST data set statistics from the match-up data base |
| + |
| + The interface should provide flexible access to a range of analytical capabilities. |
| + |
| + Input: A match-up data set generated by Use Case #3. |
| + |
| + Output: Statistical representations of the target minus comparison data set SST values. |

| + Basic course of events |
| + |
| + 1) Define refinement parameters: |
| + - nearest neighbor, |
| + - average |
| + - variance |
| + - min-max difference |
| + |
| + 2) Refine match-up |
| + - Calculate target, comparison SST-tuples (1 SST value for the target data set and 1 for point or line data sets or N-2 for N-2 field data sets); e.g., using nearest neighbor, average, bi-linear interpolation,... |
| + - Calculate statistic associated with target and comparison match-ups; e.g., variance, min-max difference, skewness,... |
| + |
| + 3) Define filter (or stratify) parameters: |
| + - space |
| + - time |
| + - refined statistic |
| + - target-comparison distance in space and time |
| + - comparison data set |
| + |
| + 4) Define statistical analyses; |
| + - histogram differences |
| + - mean and variance |
| + |
| + 5) Apply statistical analyses on the refined match-up data set target minus comparison SST value; one difference for each of the N-2 data sets in the match-up element. |
