Code Reviewer:

I developed the original lfric to radaer functionality in 2020. Like a lot of developments back then, it was needed in a hurry and so I developed a fudged solution with technical debt.

We will need user flexibility soon to be able to run radaer with different user settings, hence this part one of two development.

In part two, I will calculate the previously hard coded setting during the initialisation step and save the values so they can be accessed at runtime.
