<div dir="ltr"><div><div>Hello,<br><br></div>I want to take the three files and find the time average of the 2 meter temperature. I have this script here that calculates the mean difference of T2 for the two files given below. What I want to do is instead of just one month, I'd like to Average three months for the YSU and three months for the MYJ simulations.
