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).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 low windspeeds this formula gives wind chill temperatures that are greater than the ambient
temperature. 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.
