Measured Variables from the KCOMKRET2 WeatherUndergound weather station, all QAQC'd and gap-filled

dateTime = date and time in local Mountain Time
TempC = temperature in Degrees celcius, sensor measured
DewPointC = Dew point in degrees celcius, sensor measured
HumidityPerc = relative humidity %, sensor measured

Rad = incoming downward shortwave radiation watts/meter squared W/m2, sensor measured (begins on Feb. 1, 2012)
u = u or x (E-W) componenet of the windspeed m/s, sensor measured
v = v or y (N-S) component of the windspeed m/s, sensor measured
date = date only
