I am trying to find a good interpolation model for some precipitation data and would like to remove the elevational trend but I am unsure on the order of trend removal. I have my precip data as Dataset#1 and my DEM as Dataset#2. I was planing to use the Simple Kriging with Normal Score transformation, but don't know which trend removal order to chose for each dataset. Any info on what the orders mean (i.e. first vs constant) or best practices for elevation trend removal would be greatly appreciated.
