NOTES:
Data in column 4A are (MAX+MIN) / 2, whereas data in columns 4B, 5, 6, 15, 16, 23 are means via continuous observations
Units are: 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.
Data in columns 4B, 5, 6, 15, 16, 23 are updated continuously, there by achieving a "true" mean.
