@lizzieinvancouver before figuring out a way to include days with temperatures > 30C into the model, I checked how often these days occurred during out study period!
For daily mean temperature---the value used to calculate GDDs---we have 3 days with mean temp >30C:
date maxTempC meanTempC minTempC
566 2019-07-20 35.4 30.2 24.6
940 2020-07-27 37.8 30.1 22.4
941 2020-07-28 37.1 30.2 23.4
However, if we wish to account for daily max temperatures >30C, there is a lot more. 118 days out of our 3 years had max temperatures above 30 degrees celcius.
We could use a "double threshold" if we wish to take max temp into account. I don't remember where I read that though
