Range Notes
Wind speed is measured continuously and
stored in station memory as a series of 2
1 to 100 mph
second averages. The reported wind speed
1 to 86.9 knots
is the average over the 15 minute logging
1 to 44.7 m/s
interval. The highest measured speed during
1 to 160.9 km/hr
the logging interval is reported as the gust
value.
Wind direction is measured continuously
and stored in station memory as a series
of 2 second averages. The reported wind
direction is the average scalar direction over
1° ~ 360°
the 15 minute logging interval. The gust
direction is the average scalar direction for
the 2 second record corresponding to the
gust value.
Temperature is measured once per minute.
The reported temperature is the average
-40° to 140° F
value for the 15 minute logging interval.
-40° to 60° C
High and low temperatures are based on the
1-minute readings.
See fig S for accuracy tolerance over the
RH range. Humidity is measured once
per minute. The reported humidity is the
0 to 100%
average value for the 15 minute logging
interval. High and low RH are based on the
1-minute readings.
Pressure is measured once per minute. The
600 to 1100 mbar/hPa
reported pressure is the average value for
17.72 to 32.48 inHg
the logging interval. High and low pressures
450.0 to 825.1 mmHg
are based on the 1-minute readings.
Rainfall is measured continuously in 0.2
0 to 7.8 in/hr mm increments (tipping bucket calibration
volume)
