Column 5: Dew point is calculated from temperature and humidity and is continuously averaged for 24 hours. Data in columns 9,, are entered manually by the station observer. Columns 17-: 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,, 16, 23 are updated continuously, there by achieving a "true" mean.
