Perrin Pahlen The Montréal methodology description references a technical note that doesn't appear to exist in the dataset — it's cited but not attached. Without the note, it's impossible to assess whether the 1998 baseline is comparable to later years. Should we reconstruct the note from the source, or should we add a caveat that the early Montréal data is of unknown comparability?
value?Makes sense, thanks.
Is this the same chart as the other chart? It comes across as different.
