Dendrochronology works by comparing the sequences of variation in growth rings. Not every growing season is the same everywhere and there is more growth some years than others.

Over time massive data sets have been developed that allow growth sequences from different times, and locations to be compared.

So the variation in rings is compared to find a match.

Usually in academia these things work on a collaborative basis, so if you are part of an institution that cooperates and contributes then the data is available.
