This .PAR file produces a wind chill summary of the Mt. Logan Peak data set.
The formula for calculating wind chill is given as follows:
Te = 33-(h/22.066)
where
Te = Wind Chill equivalent temperature, degrees C
h = ((100V)
0.5
+ 10.45-V)(33-T)
where
h = Kcal m
-2
hr
-1
wind chill index
v = wind speed in meters/second
T = temperature in degrees C
Note that at wind speeds between 0 to 4 mph (0 to 1.8 m/s), the wind chill
should be ignored because this formula results in wind chill temperatures that
are greater than the ambient temperature. The National Weather Service
includes wind chill in reports only when temperatures drop below 35°F (1.7°
C).

The formula is for example purposes and is not endorsed by Campbell
Scientific as a standard.
When this .PAR file is executed, the following output is displayed on the
screen.
