- 1) Define refinement parameters: |

- |

- 2) Refine match-up |

- - Calculate target, comparison SST pairs (1 SST value for each); 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 |
