Data in column 4A are (MAX+MIN) / 2, whereas data in columns 4B, 5, 6, 15, 16, 23 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, 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: sunshine index is measured via solar cell and its value ranges from 0 (darkest) to 99 (brightest) 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. OBSERVER NOTES: Computer off-line 7/6 0500 to 7/9 1900. Daily data for this period is estimated from data from BWI Airport (10 miles to north).OBSERVATIONS AT 3-HOUR INTERVALS July 1999: Millersville 1SE
