Station charts
Rank 4,067 of 4,072 in California, Oct 4. 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.
247 score49.6of 100
The score is the weighted mean of its six parts, from the last 7 days. How a station is ranked sets out each part.
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: 66 of 672 scheduled reports received, 9.8%.
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.

Station report
Drawn from the register, in the manner of the Field Book, and opened beside the plates that explain each part of it.
At 5,141 ft above sea level, 17 per cent of the atmosphere's air lies below the station. The standard atmosphere puts the pressure there at 24.76 inHg and the temperature at 40.7 F.

FB-ENG-003, Fig. CHydrostatic balanceWhy a barometer 5,141 ft up reads less: it weighs only the air above it.
On Oct 4 the noon sun stands 51 degrees above the horizon at 34.23 N, and the day is 11 h 35 min long. Level ground there takes 78 per cent of the noon sunlight a surface facing the sun would.
