(*) Note regarding temperature values: the station datalogger polls each of the three temperature sensors once every 10 seconds, and keeps a running average of the last 30 of these 10-second samples. This "running 5-minute average" is computed every 10-seconds throughout the hour, for a total of 360 times. The temperature values reported by the station and shown above are the running 5-minute averages from the end of each of the 12 5-minute periods during the hour, and the mininum, maxium, and standard deviation of all 360 5-minute averages. Since the minimum and maximum are computed from all 360 5-minute averages, not just the 12 values shown above, the minimum may occasionally be less than, or the maximum greater than, the minimum and maximum of the 12 5-minute values shown.
