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.

Preconditions

Triggers

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.

6) Output plots, tables
