between 1 to
57 mph
0.1 mph
0.1 knot

0.1 km/hr
1 to 100 mph
1 to 86.9 knots
1 to 44.7 m/s
1 to 160.9 km/hr
Wind speed is measured continuously and
stored in station memory as a series of 2
second averages. The reported wind speed
is the average over the 15 minute logging
interval. The highest measured speed during
the logging interval is reported as the gust
value.
Wind Direction 2° 1° 1° ~ 360°
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
the 15 minute logging interval. The gust
direction is the average scalar direction for
the 2 second record corresponding to the
gust value.
Temperature
0.45° F
0.25° C
0.1° F
0.1° C
-40° to 140° F
-40° to 60° C
Temperature is measured once per minute.
The reported temperature is the average
value for the 15 minute logging interval.
High and low temperatures are based on the
1-minute readings.
Relative Humidity
(typical)
1.5% between
0 - 80%
1% 0 to 100%
See fig S for accuracy tolerance over the
RH range. Humidity is measured once
per minute. The reported humidity is the
average value for the 15 minute logging
interval. High and low RH are based on the
1-minute readings.
Absolute Pressure

600 to 1100 mbar/hPa
17.72 to 32.48 inHg
450.0 to 825.1 mmHg
Pressure is measured once per minute. The
reported pressure is the average value for
the logging interval. High and low pressures
are based on the 1-minute readings.
Rain Rate
