How the index builds, day by day
Each bar is one local day's contribution to the index. Days with a final NWS climate report count as they stand (shown as final record); a day whose report is not out yet uses the METAR figure and is marked not final; the rest are the model's estimate, with a whisker one standard deviation either way.

Settlement
KMIA is a US station, so this contract settles on the NWS daily climate report (CLI) of each of its 30 days: the index is the sum built from the high and low the National Weather Service prints. The local forecast office issues each report after local midnight, normally within one to three hours, and the contract settles one day after the last report is issued - about 12-02 07:00. A corrected report replaces the earlier one and the day runs again from it. If any day has no final report three days after the period ends, the contract is void and every position is refunded at cost. NWS CLI Watch ↗
