I have got the following problem. I have a catchment and several gauging stations measuring daily precipitation amounts. I would like to interpolate the precipitation amounts from these stations (points) to the whole catchment. In the next step I would like to calculate average precipitation value for the catchment. I can do it for one day (1 value for each station).
The problem is that I have 30 years of daily precipitation measurements in each station and so I need to do this process thousands of times. I have created a simple model in model builder which could do this process once, but I am not able to force it to do it repeatedly.

I need help how to automate this process.
