IBKR settles Paris temperature on LFPO

LFPO is Paris Orly, Paris. IBKR ForecastEx 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

IBKR ForecastEx uses LFPO (Paris Orly). Polymarket settles the same city on LFPB (Paris-Le Bourget) 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.
