    "referenceSelection": "Grounded inland reference areas were selected for multi-year spatial coverage and identifiable flow; no speed anomaly was used to select them. The 2016 pre-reference record is shown only if all common cells were observed.",
    "commonMask": "Only identical cells with finite speed and speed-error estimates in every reference year and the latest period; at least 20 of 25 required",
    "statistic": "Arithmetic mean speed across the common cells, multiplied by 365.25; source error is conservatively averaged, not reduced by square-root cell count",

    "classification": "Faster/slower only when the current mean \u00b1 twice its mean source error lies entirely outside the recent range; otherwise Within the recent range. At least 8 historical years and speed greater than twice source error required. This is a descriptive range, not a climate normal or a significance test."
