Units: Temperature=°F, Wind=mph, Pressure=Inches Hg, Precipitation=inches. Column 5: Dew point is calculated from temperature and humidity and is continuously averaged for each hour. Column 12: Resultant wind is calculated by the vector sum of continuous wind observations. Column 17: Solar Radiation is measured in Watts/m^2 and is continuously averaged for each hour. Precipitation types: 1 FOG, 2 HEAVY FOG, 3 THUNDER, 4 ICE PELLETS, 5 HAIL, 6 GLAZE, 7 DUSTSTORM, 8 SMOKE/HAZE, 9 BLOWING SNOW. Degree Days heating base is 65°F, cooling base is 65°F. Data in columns 4B, 5, 6, 10, 11, 17 are updated continuously, there by achieving a "true" mean.
