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.
Column 23: Solar Radiation is measured in Watts/m^2 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.

WEATHER NOTES SUMMARY BY HOURS

Wind Direction: Directions are those from which the wind is blowing, | | Averages | |
indicated in tens of degrees from true North: i.e., 09 for East, 18 for | +----+------+---+---+---+-----+Resultant|
South, 27 for West, and 00 or 36 for North. | | | | | | | | |
Wind Speed: The observed one-minute average speed in miles-per-hour. | | | | T | | | | Wind |
Wind Gust: The maximum instantaneous wind speed for the ten minute-period | | | | e | | % | W +----+----+
