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: 252 of 504 scheduled reports received, 50.0%.

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.
