Citizen station GW3727 Report

Rank 2,184 of 2,650 in Colorado, 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.

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: 100 of 168 scheduled reports received, 59.5%.

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.
