Calculation of UWG for several grid at the same time

As you see figure, I have divided the desired area into 200 * 200 girids and all the desired indicators have been calculated in UWG for each of them. Now I want to calculate the amount of UHI in each girid simulatniously.
if i want to make calculate one by one .it will take so long and it is inmosible
can u help me to know how to manage this problem?

If you are GIS and RS expert, I would recommend the following resource.
