Do you have a need for chill hour measurements?  There are a couple of online sources that you can use to calculate chill hours for your location.  AgroClimate has a great graphic package that allows you to pick between two chill hour models.  You can find it at


If you are in Georgia, the Georgia Automated Environmental Monitoring Network also has chill hour calculators for each of their stations which allow you to select a start and end date.  The current chill hours for all of their stations can be found at
