this set of files organized to solve 'environment' function with ranges of different variables. I followed all possible instructions but the elapse time is growing with each iteration inside the script 'Ta_I_yearly_by_azimangle' so I have to take bigger steps. Maybe the whole thing could be organized some other way to make it faster, I don't know, so I need your help here, thanks.

You should use the actual profiler. In most releases that is called 'run and time'. That will show you a breakdown by function and line by line.

You'd need to associate all of your calc's into one function file and no need to save all variable/calc values from every iteration. Save the only ones that you'd need as outputs from your main function file. ALso, put all of your external fuinction files as a nested functions within your main function file. All these steps should speed up your simulations.

The output of the profile is useful - thanks.
The most time is spent here:
[days(:,:,i), time(:,:,:,i), I(:,:,:,i), Ta(:,:,:,i), ...
angle(:,i), Ir(:,:,:,i), Id(:,:,:,i), Gincl(:,:,:,i), r(:,:,:,i)] = ...
But this takes between 36 and 376 seconds. This is not an effect inside Ta_I_yearly_by_angle.
My guess is, that your memory is exhausted and sometime the slow disk caching is used. So please check the memory consumption. during the code runs. Pre-allocating is a good programming style already, but sometimes only more RAM helps.
