Figure showing seasonal windroses
Figure 3. Ikpikpuk: Seasonal windroses. The wind direction and speed data are divided into 16 wind direction categories (22.5° each) and 3 wind speed classes: less than 5 m s−1, between 5 m s−1 and 10 m s−1, and greater than 10 m s−1. The percentage of time that wind speeds occupy each class and directional category (concentric rings) is presented for each season: winter (December, January, February), spring (March, April, May), summer (June, July, August), and autumn (September, October, November). (m s−1, meter per second; U, wind speed; N, north; E, east; S, south; W, west;) (Click image for larger version.)

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).

Table 1c. Statistical summaries of ground temperature data at 10 and 120 centimeters depth 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).
