Station charts
Rank 9 of 1,111 in Indiana, Oct 16. The 247 rank orders a state's stations by their 247 score out of 100: how reliably they report, how accurate their readings are against a reference station, how their readings pass their checks, and how they stand against the forecast.

Drawn from the register, in the manner of the Field Book, and opened beside the plates that explain each part of it.
