CALT1rank 677; behind on 247 score 91.9 against 91.7
Equal scores are ordered by the share of scheduled reports received, then the reports due in the week (the longer record first), then the median arrival, then the longest silence.

The reports received are counted from the network's own archive of this station's reports. Its 247 rank is counted from Storm Station's own record, which holds less than 7 days of it so far: 166 of 168 scheduled reports received, 98.8%.
Against its reference: each temperature this station reports is compared with the nearest airport or climate reference station that reported within half an hour, up to 15 miles away. The figure is its reading less the reference's, on average, as both were reported; the typical difference is the root mean square. The difference in height is shown where both heights are known.
Its schedule is one report every hour, 24 in 24 hours. Two reports in the same hour count as one received.

Drawn from its report of Oct 15, 2026, 10:00 PM local time, in the manner of the Field Book, and opened beside the plates that explain each part of it.
66.4 F with a dew point of 62.1 F, 86 per cent relative humidity. Air lifted from the station would cool to its dew point, where cloud forms, about 1,000 ft up.
At 913 ft above sea level, 3 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 28.95 inHg and the temperature at 55.7 F; it reports 66.4 F, 10.7 F warmer than standard.
On Oct 16 the noon sun stands 46 degrees above the horizon at 35.06 N, and the day is 11 h 08 min long. Level ground there takes 72 per cent of the noon sunlight a surface facing the sun would.
