(Daily Ave. Temp. - Base Temp.) One unit is <br />accumulated for each degree Fahrenheit the average temperature is above the base <br />temperature. Negative numbers are discarded. Example: If the days high temperature was <br />95 and the low temperature was 51, the base 60 heating degree day units is ((95 + 51) / 2) <br />- 60 = 13. This is done for each day of the month and summed. <br />Corn Growing Degree Day units have the limitations that the maximum daily <br />temperatures greater than 86 F are set to 86 F and minimums less than 50 F are set to 50 <br />F. <br />Table updated on Jul 28, _Ang <br />Months with 5 or more missing days are not considered <br />Years with 1 or more missing months are not considered <br />http://www.wrcc.dri.edu/cgi-bin/cliNIAIN.pl?cobrit
