Data in column 4A are (MAX+MIN) 2, whereas columns 4B, 5, 6, 15,, are means via continuous observations for 24 hours. Column 5: Dew point is calculated from temperature and humidity and is continuously averaged for 24 hours. Data in columns 9,, 12 are entered manually by the station observer. Columns 17-18: Resultant wind is calculated by the vector sum of continuous wind observations. Column : Solar Radiation is measured in Watts/m^2 and is continuously averaged for 24 hours. Data in columns 4B, 5, 6, 15,, are updated continuously, there by achieving a "true" mean.

Wind : s are those from which the wind is blowing, indicated in tens of degrees from true north: i.e., 9 for East, 18 for South, 27 for West, and or 36 for North. Wind : The observed one-minute average speed in miles-per-hour. Wind : The maximum instantaneous wind speed for the -minute period preceding the observation. Rate: The instantaneous rainfall at the time of observation, calculated by timing consecutive." pulses from the electronic rain gauge and interpolating this for one hour.
