Performance error metrics for measured and simulated values

Hi all!

I have some files (attached please find two of them) that contain hourly measured (.txt) and simulated values (.csv) for temperature and relative humidity. I want to calculate error statisticw (eg. mian bias, nmse, rmse, IoA, Correlation Coefficient).

Is there a toolbox that does the job or do I have to calculate them by hand?

Does anyone have experience on that?
