Tables
Table 1a. Statistical summaries of air temperature data at monthly resolution. Average, minimum, maximum, anomaly, and percentage of data available. Anomalies are calculated relative to the entire available period of record for the given site. 95 percent of the data must be available in order to calculate statistics. Periods with less than the 95 percent requirement are represented by NaN (not a number).
