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 https://agroclimate.org/tools/Chill-Hours-Calculator/.

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 past three years of chill hours for all of their stations can be found at https://weather.uga.edu/index.php?content=ch.  You can get current chill hours for individual station using calculators at their web site.
