WRF systematic biases

Hi, I met some difficulties about the model uncertainties.
How to take into account the model systematic biases (such as the uncertainties induced by physical scheme, initiation conditions and the year of simulation) in the results analysis? I used the raw results from the WRF output data to do some studies about climate effect, but there exists reviewer said that I need to correct the climatological biases between the simulations and observations (varies with time) before climate analysis and calculation. In addtion, some information about the robustness and uncertainty ranges of climatic effects also should be presented.
I'm confused about the problem. Is there anyone could help me?
Thank you very much!

I think the best approach would be to try to find some other literature that discusses the physics schemes you used and see if there are known biases mentioned. For most schemes, these exist for particular circumstances. You may be able to find some presentations that discuss some of these issues at one of our past WRF Workshops.
