Growing Degree Days, Part 2

Earlier this week, a BYGL Alert was written as an intro or refresher to growing degree days, Growing Degree Days (GDD) – What Is Your # , (March 16, 2020). As promised, here is part two.

 

Here is a look at GDD accumulations across the state  as of March 20, 2020. While I couldn’t do every Ohio zip code – but you can easily do your own – this gives you a taste of where others are at in Ohio.

 

Toledo (43615) - 26 GDD

Cleveland (44120) - 48 GDD

Canfield (44404) - 61 GDD

Athens (45701) - 92 GDD

Ironton (45638) - 101 GDD

Cincinnati (45223) - 95 GDD

Lima (45804) - 31 GDD

Mansfield (44906) - 46 GDD

Columbus (43210) - 59 GDD

Chillicothe (45601) - 96 GDD

 

Once you have your own GDD, you can click on the ‘summary’ tab and it will provide the last 6 years of GDD accumulations on that same date. I used the zip code of the office in Toledo as an example. 

 

Toledo (43615) – this year, plus 6 past years

 

2020, March 20 - 26 GDD

2019, March 20 - 74 GDD                          

2018, March 20 - 109 GDD

2017, March 20 - 152 GDD

2016, March 20 -152 GDD

2015, March 20 - 41 GDD

2014, March 20 - 49 GDD

 

Just as you can change the zip code on the website, you can also manipulate the date if you would like to explore what was the GDD on a specific date in the past. If you have any questions, or need additional guidance to navigate the website if you are a newbie, send an email to stone.91@osu.edu and in the subject line include: GDD
