DESCRIPTION OF lIONTHLT DATA <br />1,2,3 -- Mean max loon, minimun, average temperature in 0.1 degrees F. <br />19999 = more than 9 days missing <br />10000 + value = 1-9 days missing <br />99999 = missing ve Lue <br />4 -- Heating degree days -- 65 degree F base. <br />99999 = missing value <br />5,6 -- Highest/Lowest tenQereture end date. <br />These data are pecked so that the lest two digits of the <br />mmber indicate the date and the first 1-3 di pits are the <br />tmgerature (TTTDD). <br />99999 = missing <br />Date + 50 = nulti ple occurenee <br />Negative value = negative temperature <br />7 -- Number of days with max. tang. greeter than or equal to 90 and <br />number of days with max. tenQ, less than or equal to 32. <br />These data are packed so that the lest two digits irdiee[e <br />max. tang less than or equal 32 and the first 1 or 2 <br />indicate max. temp. greater than or equal to 90. <br />8 •- Number of days with min. temp, less than or equal to 32 end <br />rnnber of days with min. temp, less than or equal to 0. <br />These data are packed similar to IW. <br />9 -- Total nanthly precipitation in 0.01 inches. <br />• 99999 missing <br />199998 = estimated trace <br />100000 + value = estimated value <br />200000 + value = interpolated value <br />99997 = eccunulated period <br />399998 accumulated trace <br />300000 + value = accumul aced value <br />99998 = trace <br />10 -- Total monthly snowfall in 0.1 inches. <br />999999 = missing value <br />100000 + value = accumulated value <br />99999 = trace <br />11 -- Greatest anpunt of precipitation in 0.01 inches <br />199998 = estimated [race <br />100000 + value = estimated value <br />919999 or 999999 = missing value <br />99999 = trace <br />12 -- Greatest snow depth in inches. <br />9998 = trace <br />9999 = missing <br />13 -- Dates of greatest amount of precipitation end greatest snow depth <br />Packed similar to p4 (PP55) <br />14 -- Number of days with precipitation greater than 0.1 inches, <br />0.5 inches and 1.0 inches <br />These values are packed so that the last two digits are the <br />number of days with prec. > 1.0, the middle digits indicate the <br />number of days with prec. > 0.5 and the the first 1 or 2 <br />digits are the number of days with prec. > 0.1 inches. <br />99 = missing <br />• 15 -- Number of days with hail and number of days with one ineh or <br />more of snow on the ground <br />These data are packed similar to IW.
