MEMBERS 50 runs of one model · RUN-TO-RUN the same date re-forecast · MODELS between seven independent centres (ECMWF, GFS, ICON, Met Office, Météo-France, JMA, Canada).
white border + ! = ensemble mean already exceeds the FoM limit
no data — voids the score for that day
not applicable this phase
italic blue = advisory level above the mission altitude requirement: analysed for the ceiling, excluded from the exceedance combination
struck through = non-traversable, climb arrested at a subjacent level
red hatch on the criteria score = hour disqualified by the altitude requirement, whatever the score reads
white dot = T-72h empirical escalation applied
▲ under an hour = operative slot: the best hour in an elective window (launch / recovery)
·blue hour = D+1, the recovery window falls on the night after launch
↑ ↓ = hour containing sunrise / sunset; shaded hour columns are dark
dotted border = deterministic backfill. Value from a single run; its spread is
modelled, not measured. Do not let a dotted cell carry a marginal GO.
ENSEMBLE every scoring input from real ensemble spread
MIXED some hours backfilled
DETERMINISTIC all hours backfilled — treat probabilities as indicative
