Temperature readings fromthe weather station left at the crimescene are also included.A correction factor has been appliedto the daily average. The correctionfactor has been calculated by thefollowing method: the average of thedifference between Ave1 (perth) andAve 2 (weather station). The resultantcorrection factor has been appliedto each daily average temperaturefrom Perth data for the days prior tothe body being found. Ave3 columnholds these data.Degree days have also beencalculated by subtracting the lowerdevelopment threshold (10 o C) fromthe corrected daily average (Ave3).ADH or accumulated degree hourshas been calculated: Degree days x24 hours.http://www.bom.gov.auNB: students are expected to completetheir own calculations.19
