means via continuous observations Units: Temperature=°F, Wind=mph, Pressure=Inches Hg, Precipitation=inches. for 24 hours. Column 5: Dew point is calculated from temperature and humidity and is continuously averaged for 24 hours. Columns 7, 8: Degree Days heating base is 65°F, cooling base is 65°F. Data in columns 9, 10, 12 are entered manually by the station observer. Columns 17-18: Resultant wind is calculated by the vector sum of continuous wind observations. Column 23: Solar Radiation is measured in Watts/m² and is continuously averaged for 24 hours. Data in columns 4B, 5, 6, 15, 16, 23 are updated continuously, there by achieving a "true" mean.
