Figure showing mean-daily air temperature
Figure 3. Awuna1: Mean-daily air temperature (blue dots) calculated using the entire available data record from this site. Also shown is the range of daily variability (vertical lines); mean-daily air temperatures fall within this range 95% of the time. (Click image for larger version.)


Figure showing range of daily variability in air temperature
Figure 4. Awuna1: Range of daily variability in air temperature for each day of the year. Mean-daily air temperatures fall within this range 95% of the time. Air temperatures are much more variable during the cold winter season than during the summer. (Click image for larger version.)


Figure showing mean-monthly air temperature
Figure 5. Awuna1: Mean-monthly air temperature (blue dots, left panel) calculated using the entire available data record from this site. Also shown is the range of monthly variability (vertical lines, left panel and vertical bars, right panel); mean-monthly air temperatures fall within this range 95% of the time.

Figure showing mean seasonal air temperature
Figure 6. Awuna1: Mean seasonal air temperature (blue dots, left panel) calculated using the entire available data record from this site. Also shown is the range of seasonal variability (vertical lines, left panel and vertical bars, right panel); mean seasonal air temperatures fall within this range 95% of the time.

Tables

Table 1a. Statistical summaries of provisional 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% of the data must be available in order to calculate statistics. Periods with less than the 95% requirement are represented by NaN (not a number).
