  NOTES:
   Data in columns 4, 5, 6, 10, 11, 17 are means via continuous observations for each hour.
   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/m² 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.
