Polymarket settles Paris temperature on LFPB

LFPB is Paris-Le Bourget, Paris. Polymarket settles temperature contracts here. Below: the resolution source each venue names, when the station reports, and how long a reading takes to reach the public feed.

This city settles on two different stations

Polymarket uses LFPB (Paris-Le Bourget). IBKR ForecastEx settles the same city on LFPO (Paris Orly) instead. The two sites can report different temperatures at the same moment and land in different contract buckets on the same day, so a reading from one tells you nothing definitive about the other.
